# From Paul Eggert (2017-02-10):
|

#
|

# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),

# San Diego: ACS Publications, Inc. (2003).
|

# Unfortunately this book contains many errors and cites no sources.
|
||
#
|
||
# Many years ago Gwillim Law wrote that a good source
|
||
# for time zone data was the International Air Transport
|
||
# Association's Standard Schedules Information Manual (IATA SSIM),
|
||
# published semiannually. Law sent in several helpful summaries
|
||
# of the IATA's data after 1990. Except where otherwise noted,
|
||
# IATA SSIM is the source for entries after 1990.
|
||
#
|
||
# A reliable and entertaining source about time zones is
|
||
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
|
||
#
|
||
# Except where otherwise noted, Shanks & Pottenger is the source for

|
||
# Britain (United Kingdom) and Ireland (Eire)
|
||
|
||
# From Peter Ilieve (1994-07-06):
|
||
#
|
||
# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
|
||
# historical vistas along the Thames in west London. There was a photo
|
||
# and a sketch map showing some of the sightlines involved. One paragraph
|
||
# of the text said:
|
||
#
|
||
# 'An old stone obelisk marking a forgotten terrestrial meridian stands
|
||
# beside the river at Kew. In the 18th century, before time and longitude
|
||
# was standardised by the Royal Observatory in Greenwich, scholars observed
|
||
# this stone and the movement of stars from Kew Observatory nearby. They
|
||
# made their calculations and set the time for the Horse Guards and Parliament,
|
||
# but now the stone is obscured by scrubwood and can only be seen by walking
|
||
# along the towpath within a few yards of it.'
|
||
#
|
||
# I have a one inch to one mile map of London and my estimate of the stone's
|
||
# position is 51° 28' 30" N, 0° 18' 45" W. The longitude should
|
||
# be within about ±2". The Ordnance Survey grid reference is TQ172761.
|
||
#
|
||
# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
|
||
|
||
# From Paul Eggert (1993-11-18):
|
||
#
|
||
# Howse writes that Britain was the first country to use standard time.
|
||
# The railways cared most about the inconsistencies of local mean time,
|
||
# and it was they who forced a uniform time on the country.
|
||
# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
|
||
# and was popularized by Abraham Follett Osler (1808-1903).
|
||
# The first railway to adopt London time was the Great Western Railway
|
||
# in November 1840; other railways followed suit, and by 1847 most
|
||
# (though not all) railways used London time. On 1847-09-22 the
|
||
# Railway Clearing House, an industry standards body, recommended that GMT be
|
||
# adopted at all stations as soon as the General Post Office permitted it.
|
||
# The transition occurred on 12-01 for the L&NW, the Caledonian,
|
||
# and presumably other railways; the January 1848 Bradshaw's lists many
|
||
# railways as using GMT. By 1855 the vast majority of public
|
||
# clocks in Britain were set to GMT (though some, like the great clock
|
||
# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
|
||
# one for local time and one for GMT). The last major holdout was the legal
|
||
# system, which stubbornly stuck to local time for many years, leading
|
||
# to oddities like polls opening at 08:13 and closing at 16:13.
|
||
# The legal system finally switched to GMT when the Statutes (Definition
|
||
# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
|
||
#
|
||
# In the tables below, we condense this complicated story into a single
|
||
# transition date for London, namely 1847-12-01. We don't know as much
|
||
# about Dublin, so we use 1880-08-02, the legal transition time.
|
||
|
||
# From Paul Eggert (2014-07-19):
|
||
# The ancients had no need for daylight saving, as they kept time
|
||
# informally or via hours whose length depended on the time of year.
|
||
# Daylight saving time in its modern sense was invented by the
|
||
# New Zealand entomologist George Vernon Hudson (1867-1946),
|
||
# whose day job as a postal clerk led him to value
|
||
# after-hours daylight in which to pursue his research.
|
||
# In 1895 he presented a paper to the Wellington Philosophical Society
|
||
# that proposed a two-hour daylight-saving shift. See:
|
||
# Hudson GV. On seasonal time-adjustment in countries south of lat. 30°.
|
||
# Transactions and Proceedings of the New Zealand Institute. 1895;28:734
|
||
# http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
|
||
# Although some interest was expressed in New Zealand, his proposal
|
||
# did not find its way into law and eventually it was almost forgotten.
|
||
#
|
||
# In England, DST was independently reinvented by William Willett (1857-1915),
|
||
# a London builder and member of the Royal Astronomical Society
|
||
# who circulated a pamphlet "The Waste of Daylight" (1907)
|
||
# that proposed advancing clocks 20 minutes on each of four Sundays in April,
|
||
# and retarding them by the same amount on four Sundays in September.
|
||
# A bill was drafted in 1909 and introduced in Parliament several times,
|
||
# but it met with ridicule and opposition, especially from farming interests.
|
||
# Later editions of the pamphlet proposed one-hour summer time, and
|
||
# it was eventually adopted as a wartime measure in 1916.
|
||
# See: Summer Time Arrives Early, The Times (2000-05-18).
|
||
# A monument to Willett was unveiled on 1927-05-21, in an open space in
|
||
# a 45-acre wood near Chislehurst, Kent that was purchased by popular
|
||
# subscription and open to the public. On the south face of the monolith,
|
||
# designed by G. W. Miller, is the William Willett Memorial Sundial,
|
||
# which is permanently set to Summer Time.
|
||
|
||
# From Winston Churchill (1934-04-28):
|
||
# It is one of the paradoxes of history that we should owe the boon of
|
||
# summer time, which gives every year to the people of this country
|
||
# between 160 and 170 hours more daylight leisure, to a war which
|
||
# plunged Europe into darkness for four years, and shook the
|
||
# foundations of civilization throughout the world.

|
||
|
||
# From Paul Eggert (2015-08-08):
|
||
# The OED Supplement says that the English originally said "Daylight Saving"
|
||
# when they were debating the adoption of DST in 1908; but by 1916 this
|
||
# term appears only in quotes taken from DST's opponents, whereas the
|
||
# proponents (who eventually won the argument) are quoted as using "Summer".
|
||
# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see:
|
||
# Viscount Samuel. Leisure in a Democracy. Cambridge University Press
|
||
# ISBN 978-1-107-49471-8 (1949, reissued 2015), p 8.
|
||
|
||
# From Arthur David Olson (1989-01-19):
|
||
# A source at the British Information Office in New York avers that it's
|
||
# known as "British" Summer Time in all parts of the United Kingdom.
|
||
|
||
# Date: 4 Jan 89 08:57:25 GMT (Wed)
|
||
# From: Jonathan Leffler
|
||
# [British Summer Time] is fixed annually by Act of Parliament.
|
||
# If you can predict what Parliament will do, you should be in
|
||
# politics making a fortune, not computing.
|
||
|
||
# From Chris Carrier (1996-06-14):
|
||
# I remember reading in various wartime issues of the London Times the
|
||
# acronym BDST for British Double Summer Time. Look for the published
|
||
# time of sunrise and sunset in The Times, when BDST was in effect, and
|
||
# if you find a zone reference it will say, "All times B.D.S.T."
|
||
|
||
# From Joseph S. Myers (1999-09-02):
|
||
# ... some military cables (WO 219/4100 - this is a copy from the
|
||
# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516)
|
||
# agree that the usage is BDST (this appears in a message dated 17 Feb 1945).
|
||
|
||
# From Joseph S. Myers (2000-10-03):
|
||
# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir
|
||
# Alexander Maxwell of the Home Office asking whether there was any
|
||
# official designation; the reply of the 21st was that there wasn't
|
||
# but he couldn't think of anything better than the "Double British
|
||
# Summer Time" that the BBC had been using informally.

|
||
# https://www.polyomino.org.uk/british-time/ho-19410421.png
|
||
|
||
# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21):
|
||
# [N]o official designation has as far as I know been adopted for the time
|
||
# which is to be introduced in May....
|
||
# I cannot think of anything better than "Double British Summer Time"
|
||
# which could not be said to run counter to any official description.
|
||
|
||
# From Paul Eggert (2000-10-02):
|
||
# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common
|
||
# and follows the more usual convention of putting the location name first,
|
||
# so we use 'BDST'.
|
||
|
||
# Peter Ilieve (1998-04-19) described at length
|
||
# the history of summer time legislation in the United Kingdom.
|
||
# Since 1998 Joseph S. Myers has been updating
|
||
# and extending this list, which can be found in
|
||
# https://www.polyomino.org.uk/british-time/
|
||
|
||
# From Joseph S. Myers (1998-01-06):
|
||
#
|
||
# The legal time in the UK outside of summer time is definitely GMT, not UTC;
|
||
# see Lord Tanlaw's speech
|
||
# https://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/70611-10.htm#70611-10_head0
|
||
# (Lords Hansard 11 June 1997 columns 964 to 976).
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
#
|
||
# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948.
|
||
#
|
||
# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger
|
||
# are incorrect:
|
||
# * Wales did not switch from GMT to daylight saving time until
|
||
# 1921 Apr 3, when they began to conform with the rest of Great Britain.
|
||
# Actually, Wales was identical after 1880.
|
||
# * Eire had two transitions on 1916 Oct 1.
|
||
# It actually just had one transition.
|
||
# * Northern Ireland used single daylight saving time throughout WW II.
|
||
# Actually, it conformed to Britain.
|
||
# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
|
||
# Actually, that date saw the usual switch to summer time.
|
||
# Standard time was not changed until 1968-10-27 (the clocks didn't change).
|
||
#
|
||
# Here is another incorrect claim by Shanks & Pottenger:
|
||
# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
|
||
# to daylight saving time until 1921 Apr 3, when they began to
|
||
# conform with Great Britain.
|
||
# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
|
||
#
|
||
# The following claim by Shanks & Pottenger is possible though doubtful;
|
||
# we'll ignore it for now.
|
||
# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
|
||
|
||
# From Paul Eggert (2017-12-04):
|
||
#
|
||
# Dunsink Observatory (8 km NW of Dublin's center) was to Dublin as
|
||
# Greenwich was to London. For example:
|
||
#
|
||
# "Timeball on the ballast office is down. Dunsink time."
|
||
# -- James Joyce, Ulysses
|
||
#
|
||
# The abbreviation DMT stood for "Dublin Mean Time" or "Dunsink Mean Time";
|
||
# this being Ireland, opinions differed.
|
||
#
|
||
# Whitman says Dublin/Dunsink Mean Time was UT-00:25:21, which agrees
|
||
# with measurements of recent visitors to the Meridian Room of Dunsink
|
||
# Observatory; see Malone D. Dunsink and timekeeping. 2016-01-24.
|
||
# <https://www.maths.tcd.ie/~dwmalone/time/dunsink.html>. Malone
|
||
# writes that the Nautical Almanac listed UT-00:25:22 until 1896, when
|
||
# it moved to UT-00:25:21.1 (I confirmed that the 1893 edition used
|
||
# the former and the 1896 edition used the latter). Evidently the
|
||
# news of this change propagated slowly, as Milne 1899 still lists
|
||
# UT-00:25:22 and cites the International Telegraph Bureau. As it is
|
||
# not clear that there was any practical significance to the change
|
||
# from UT-00:25:22 to UT-00:25:21.1 in civil timekeeping, omit this
|
||
# transition for now and just use the latter value, omitting its
|
||
# fraction since our format cannot represent fractions.
|
||
|
||
# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time
|
||
# was among various actions undertaken by the 'English' government that
|
||
# would 'put the whole country into the SF (Sinn Féin) camp'. She claimed
|
||
# Irish 'public feeling (was) outraged by forcing of English time on us'."

||
# If, say, the British police were called to the station for some reason,
|
||
# I would expect the official police report to use GMT/BST and not CET/CEST.
|
||
# This is a borderline case, but for now let's stick to GMT/BST.
|
||
|
||
# From an anonymous contributor (1996-06-02):
|
||
# The law governing time in Ireland is under Statutory Instrument SI 395/94,
|
||
# which gives force to European Union 7th Council Directive No. 94/21/EC.
|
||
# Under this directive, the Minister for Justice in Ireland makes appropriate
|
||
# regulations. I spoke this morning with the Secretary of the Department of
|
||
# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
|
||
# "Irish Summer Time", abbreviated to "IST".
|
||
#
|
||
# From Paul Eggert (2017-12-07):
|
||
# The 1996 anonymous contributor's goal was to determine the correct
|
||
# abbreviation for summer time in Dublin and so the contributor
|
||
# focused on the "IST", not on the "Irish Summer Time". Though the
|
||
# "IST" was correct, the "Irish Summer Time" appears to have been an
|
||
# error, as Ireland's Standard Time (Amendment) Act, 1971 states that
|
||
# standard time in Ireland remains at UT +01 and is observed in
|
||
# summer, and that Greenwich mean time is observed in winter. (Thanks
|
||
# to Derick Rethans for pointing out the error.) That is, when
|
||
# Ireland amended the 1968 act that established UT +01 as Irish
|
||
# Standard Time, it left standard time unchanged and established GMT
|
||
# as a negative daylight saving time in winter. So, in this database
|
||
# IST stands for Irish Summer Time for timestamps before 1968, and for
|
||
# Irish Standard Time after that. See:

# From Paul Eggert (2018-02-15):
|
||
# In January 2018 we discovered that the negative SAVE values in the
|
||
# Eire rules cause problems with tests for ICU:
|
||
# https://mm.icann.org/pipermail/tz/2018-January/025825.html
|
||
# and with tests for OpenJDK:
|
||
# https://mm.icann.org/pipermail/tz/2018-January/025822.html
|
||
#
|
||
# To work around this problem, the build procedure can translate the
|
||
# following data into two forms, one with negative SAVE values and the
|
||
# other form with a traditional approximation for Irish timestamps
|
||
# after 1971-10-31 02:00 UTC; although this approximation has tm_isdst
|
||
# flags that are reversed, its UTC offsets are correct and this often
|
||
# suffices. This source file currently uses only nonnegative SAVE
|
||
# values, but this is intended to change and downstream code should
|
||
# not rely on it.
|
||
#
|
||
# The following is like GB-Eire and EU, except with standard time in
|
||
# summer and negative daylight saving time in winter. It is for when
|
||
# negative SAVE values are used.

# From Jesper Nørgaard Welen (2005-04-26):
|

# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law
|
||
# [introducing standard time] was in effect from 1894-01-01....
|
||
# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL
|
||
# confirms this, and states that the law was put forth 1893-03-29.
|
||
#
|
||
# The EU [actually, EEC and Euratom] treaty with effect from 1973:
|
||
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL
|
||
#
|
||
# This provoked a new law from 1974 to make possible summer time changes
|
||
# in subsequent decrees with the law
|
||
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL
|
||
#
|
||
# It seems however that no decree was set forward until 1980. I have
|
||
# not found any decree, but in another related law, the effecting DST
|
||
# changes are stated explicitly to be from 1980-04-06 at 02:00 to
|
||
# 1980-09-28 at 02:00. If this is true, this differs slightly from
|
||
# the EU rule in that DST runs to 02:00, not 03:00. We don't know
|
||
# when Denmark began using the EU rule correctly, but we have only
|
||
# confirmation of the 1980-time, so I presume it was correct in 1981:
|
||
# The law is about the management of the extra hour, concerning
|
||
# working hours reported and effect on obligatory-rest rules (which
|
||
# was suspended on that night):
|
||
# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL
|

|

# From Jesper Nørgaard Welen (2005-06-11):

# The Herning Folkeblad (1980-09-26) reported that the night between
|
||
# Saturday and Sunday the clock is set back from three to two.
|
||
|
||
# From Paul Eggert (2005-06-11):
|
||
# Hence the "02:00" of the 1980 law refers to standard time, not

# Greenland joined the European Communities as part of Denmark,
|
||
# obtained home rule on 1979-05-01, and left the European Communities
|
||
# on 1985-02-01. It therefore should have been using EU

|
||
# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU

# rules since at least 1991. Assume EU rules since 1980.
|

|
||
# From Gwillim Law (2001-06-06), citing
|
||
# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
|
||
# and with translations corrected by Steffen Thorsen:
|
||
#
|
||
# Greenland has four local times, and the relation to UTC
|
||
# is according to the following time line:
|
||
#
|
||
# The military zone near Thule UTC-4
|
||
# Standard Greenland time UTC-3
|
||
# Scoresbysund UTC-1
|
||
# Danmarkshavn UTC
|
||
#
|
||
# In the military area near Thule and in Danmarkshavn DST will not be
|
||
# introduced.
|
||
|
||
# From Rives McDow (2001-11-01):
|
||
#
|
||
# I correspond regularly with the Dansk Polarcenter, and wrote them at
|
||
# the time to clarify the situation in Thule. Unfortunately, I have
|
||
# not heard back from them regarding my recent letter. [But I have
|
||
# info from earlier correspondence.]
|
||
#
|
||
# According to the center, a very small local time zone around Thule
|
||
# Air Base keeps the time according to UTC-4, implementing daylight
|
||
# savings using North America rules, changing the time at 02:00 local time....
|
||
#
|
||
# The east coast of Greenland north of the community of Scoresbysund
|
||
# uses UTC in the same way as in Iceland, year round, with no dst.
|
||
# There are just a few stations on this coast, including the
|
||
# Danmarkshavn ICAO weather station mentioned in your September 29th
|
||
# email. The other stations are two sledge patrol stations in
|
||
# Mestersvig and Daneborg, the air force base at Station Nord, and the
|
||
# DPC research station at Zackenberg.
|
||
#
|
||
# Scoresbysund and two small villages nearby keep time UTC-1 and use
|
||
# the same daylight savings time period as in West Greenland (Godthåb).
|
||
#
|
||
# The rest of Greenland, including Godthåb (this area, although it
|
||
# includes central Greenland, is known as west Greenland), keeps time
|
||
# UTC-3, with daylight savings methods according to European rules.
|
||
#
|
||
# It is common procedure to use UTC 0 in the wilderness of East and
|
||
# North Greenland, because it is mainly Icelandic aircraft operators
|
||
# maintaining traffic in these areas. However, the official status of
|
||
# this area is that it sticks with Godthåb time. This area might be
|
||
# considered a dual time zone in some respects because of this.
|
||
|
||
# From Rives McDow (2001-11-19):
|
||
# I heard back from someone stationed at Thule; the time change took place
|
||
# there at 2:00 AM.
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
# From 1997 on the CIA map shows Danmarkshavn on GMT;
|
||
# the 1995 map as like Godthåb.
|
||
# For lack of better info, assume they were like Godthåb before 1996.
|
||
# startkart.no says Thule does not observe DST, but this is clearly an error,
|
||
# so go with Shanks & Pottenger for Thule transitions until this year.
|
||
# For 2007 on assume Thule will stay in sync with US DST rules.

# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,

# Iceland
|

#
|
||
# From Adam David (1993-11-06):
|
||
# The name of the timezone in Iceland for system / mail / news purposes is GMT.
|
||
#
|
||
# (1993-12-05):
|
||
# This material is paraphrased from the 1988 edition of the University of
|
||
# Iceland Almanak.
|
||
#
|
||
# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
|
||
# behind GMT. Previously, local mean solar time was used in different parts
|
||
# of Iceland, the almanak had been based on Reykjavik mean solar time which
|
||
# was 1 hour and 28 minutes behind GMT.
|
||
#
|
||
# "first day of winter" referred to [below] means the first day of the 26 weeks
|
||
# of winter, according to the old icelandic calendar that dates back to the
|
||
# time the norsemen first settled Iceland. The first day of winter is always
|
||
# Saturday, but is not dependent on the Julian or Gregorian calendars.
|
||
#
|
||
# (1993-12-10):
|
||
# I have a reference from the Oxford Icelandic-English dictionary for the
|
||
# beginning of winter, which ties it to the ecclesiastical calendar (and thus
|
||
# to the julian/gregorian calendar) over the period in question.
|
||
# the winter begins on the Saturday next before St. Luke's day
|
||
# (old style), or on St. Luke's day, if a Saturday.
|
||
# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
|
||
# might be a reference to the Julian calendar as opposed to Gregorian, or it
|
||
# might mean something else (???).

# http://lex.justice.md/viewdoc.php?action=view&view=doc&id=298782&lang=2
|
||
# ... says that since 1990-05-06 on the territory of the Moldavian SSR
|
||
# time would be calculated as the standard time of the second time belt
|
||
# plus one hour of the "summer" time. To implement that clocks would be

# time would be cancelled last Sunday of September at 3:00 and

# reintroduced last Sunday of March at 2:00.
|
||
|
||
# From Paul Eggert (2006-03-22):

# A previous version of this database followed Shanks & Pottenger, who write
|
||
# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
|
||
# However, this is most likely an error, as Moldova declared independence
|
||
# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
|
||
# In early 1992 there was large-scale interethnic violence in the area

# and it's possible that some Russophones continued to observe Moscow time.

# But [two people] separately reported via

# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
|
||
# Amsterdam mean time) onwards, the whole of the Netherlands (including
|
||
# the Dutch railways) was required by law to observe Amsterdam mean time
|
||
# (19 minutes 32.13 seconds ahead of GMT). This had already been the
|
||
# common practice (except for the railways) for many decades but it was
|
||
# not until 1909 when the Dutch government finally defined this by law.
|
||
# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
|
||
# was generally known as Dutch Time ("Nederlandse Tijd").
|
||
#
|
||
# (2001-04-08):
|
||
# 1892-05-01 was the date when the Dutch railways were by law required to
|
||
# observe GMT while the remainder of the Netherlands adhered to the common
|
||
# practice of following Amsterdam mean time.
|
||
#
|
||
# (2001-04-09):
|
||
# In 1835 the authorities of the province of North Holland requested the
|
||
# municipal authorities of the towns and cities in the province to observe
|
||
# Amsterdam mean time but I do not know in how many cases this request was
|
||
# actually followed.
|
||
#
|
||
# From 1852 onwards the Dutch telegraph offices were by law required to
|
||
# observe Amsterdam mean time. As the time signals from the observatory of
|
||
# Leiden were also distributed by the telegraph system, I assume that most
|
||
# places linked up with the telegraph (and railway) system automatically
|
||
# adopted Amsterdam mean time.
|
||
#
|
||
# Although the early Dutch railway companies initially observed a variety
|
||
# of times, most of them had adopted Amsterdam mean time by 1858 but it
|
||
# was not until 1866 when they were all required by law to observe
|
||
# Amsterdam mean time.

# Svalbard & Jan Mayen
|
||
|
||
# From Steffen Thorsen (2001-05-01):
|
||
# Although I could not find it explicitly, it seems that Jan Mayen and
|
||
# Svalbard have been using the same time as Norway at least since the
|
||
# time they were declared as parts of Norway. Svalbard was declared
|
||
# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
|
||
# Mayen by law of 1930-02-27 no 2, section 2. (From
|
||
# <http://www.lovdata.no/all/nl-19250717-011.html> and
|
||
# <http://www.lovdata.no/all/nl-19300227-002.html>). The law/regulation
|
||
# for normal/standard time in Norway is from 1894-06-29 no 1 (came
|
||
# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
|
||
# part of this law since 1925/1930. (From
|
||
# <http://www.lovdata.no/all/nl-18940629-001.html>) I have not been
|
||
# able to find if Jan Mayen used a different time zone (e.g. -0100)
|
||
# before 1930. Jan Mayen has only been "inhabited" since 1921 by
|
||
# Norwegian meteorologists and maybe used the same time as Norway ever
|
||
# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
|
||
# before 1895, and therefore probably changed the local time somewhere
|
||
# between 1895 and 1925 (inclusive).
|
||
|
||
# From Paul Eggert (2013-09-04):
|
||
#
|
||
# Actually, Jan Mayen was never occupied by Germany during World War II,
|
||
# so it must have diverged from Oslo time during the war, as Oslo was
|
||
# keeping Berlin time.
|
||
#
|
||
# <https://www.jan-mayen.no/history.htm> says that the meteorologists
|
||
# burned down their station in 1940 and left the island, but returned in
|
||
# 1941 with a small Norwegian garrison and continued operations despite
|
||
# frequent air attacks from Germans. In 1943 the Americans established a
|
||
# radiolocating station on the island, called "Atlantic City". Possibly
|
||
# the UT offset changed during the war, but I think it unlikely that
|
||
# Jan Mayen used German daylight-saving rules.
|
||
#
|
||
# Svalbard is more complicated, as it was raided in August 1941 by an
|
||
# Allied party that evacuated the civilian population to England (says
|
||
# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
|
||
# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
|
||
# expelled on 1942-05-14. However, small parties of Germans did return,
|
||
# and according to Wilhelm Dege's book "War North of 80" (1954)
|
||
# http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html
|
||
# the German armed forces at the Svalbard weather station code-named
|
||
# Haudegen did not surrender to the Allies until September 1945.
|

|
||
# Round the old offset to -0:36:45. This agrees with Willett....
|
||
#
|
||
# From Michael Deckers (2018-02-15):
|
||
# article 5 [of the 1911 decree; Deckers's translation] ...:
|
||
# These dispositions shall enter into force at the instant at which,

||
# according to the 2nd article, the civil day January 1, 1912 begins,
|
||
# all clocks therefore having to be advanced or set back correspondingly ...
|

|

# From Rui Pedro Salgueiro (1992-11-12):

# Portugal has recently (September, 27) changed timezone

# (from WET to MET or CET) to harmonize with EEC.
|

# Martin Bruckmann (1996-02-29) reports via Peter Ilieve

# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!

# I do not know why they have decided to make this change;

# as far as I remember it was done exactly during winter->summer switching

# so we (Novosibirsk) simply did not switch.

#
|
||
# From Andrey A. Chernov (1996-10-04):
|
||
# 'MSK' and 'MSD' were born and used initially on Moscow computers with

||
# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
|
||
# The next step was the UUCP network, the Relcom predecessor

# still follows Moscow time, no matter where in Russia it is located.

#
|
||
# For Grozny, Chechnya, we have the following story from
|
||
# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
|
||
# News - often false - is spread by word of mouth. A rumor that it was
|
||
# time to move the clocks back put this whole city out of sync with
|
||
# the rest of Russia for two weeks - even soldiers stationed here began
|
||
# enforcing curfew at the wrong time.
|
||
#
|
||
# From Gwillim Law (2001-06-05):
|
||
# There's considerable evidence that Sakhalin Island used to be in
|
||
# UTC+11, and has changed to UTC+10, in this decade. I start with the
|
||
# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
|
||
# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
|
||
# since September 1997.... Although the Kuril Islands are
|
||
# administratively part of Sakhalin oblast', they appear to have
|
||
# remained on UTC+11 along with Magadan.

# says that the 1956 decision to change time belts' borders was not

# implemented as planned in 1956 and the change happened in 1957.
|
||
# There is also the problem that actual time zones were different from

# numerous exceptions to application of time belt rules. For example,

# The second Nauka i Zhizn article says that in addition to

# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger:
|
||
#
|
||
# The law "Svensk författningssamling 1878, no 14" about standard time in 1879:
|
||
# From the beginning of 1879 (that is 01-01 00:00) the time for all
|
||
# places in the country is "the mean solar time for the meridian at
|
||
# three degrees, or twelve minutes of time, to the west of the
|
||
# meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
|
||
#
|
||
# The observatory at that time had the meridian 18° 03' 30"
|
||
# eastern longitude = 01:12:14 in time. Less 12 minutes gives the
|
||
# national standard time as 01:00:14 ahead of GMT....
|
||
#
|
||
# About the beginning of CET in Sweden. The lawtext ("Svensk
|
||
# författningssamling 1899, no 44") states, that "from the beginning
|
||
# of 1900... ... the same as the mean solar time for the meridian at
|
||
# the distance of one hour of time from the meridian of the English
|
||
# observatory at Greenwich, or at 12 minutes 14 seconds to the west
|
||
# from the meridian of the Observatory of Stockholm". The law is dated
|
||
# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
|
||
# in Sweden is 01:00:00 ahead of GMT.
|
||
#
|
||
# 1916: The lawtext ("Svensk författningssamling 1916, no 124") states
|
||
# that "1916-05-15 is considered to begin one hour earlier". It is
|
||
# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
|
||
# Further the law says, that "1916-09-30 is considered to end one hour later".
|
||
#
|
||
# The laws regulating [DST] are available on the site of the Swedish

# summertime the church-clocks etc were set back one hour to show

# I have researched the DST usage in Switzerland during the 1940ies.
|

#
|
||
# As I wrote in an earlier message, I suspected the current tzdata values
|
||
# to be wrong. This is now verified.
|

#
|
||
# I have found copies of the original ruling by the Swiss Federal
|
||
# government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss
|
||
# federal law collection)...
|
||
#
|
||
# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am
|
||
# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am.

#
|

# DST began on Monday, 4 May 1942 at 01:00 am
|
||
# DST ended on Monday, 5 Oct 1942 at 02:00 am
|
||
#
|
||
# There was no DST in 1940, I have checked the law collection carefully.
|
||
# It is also indicated by the fact that the 1942 entry in the law
|
||
# collection points back to 1941 as a reference, but no reference to any
|
||
# other years are made.
|
||
#
|
||
# Newspaper articles I have read in the archives on 6 May 1941 reported
|
||
# about the introduction of DST (Sommerzeit in German) during the previous
|
||
# night as an absolute novelty, because this was the first time that such
|
||
# a thing had happened in Switzerland.
|
||
#
|
||
# I have also checked 1916, because one book source (Gabriel, Traité de
|
||
# l'heure dans le monde) claims that Switzerland had DST in 1916. This is
|
||
# false, no official document could be found. Probably Gabriel got misled
|
||
# by references to Germany, which introduced DST in 1916 for the first time.
|
||
#
|
||
# The tzdata rules for Switzerland must be changed to:
|
||
# Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S

# One further detail for Switzerland, which is probably out of scope for
|
||
# most users of tzdata: The [Europe/Zurich zone] ...
|
||
# describes all of Switzerland correctly, with the exception of
|
||
# the Canton de Genève (Geneva, Genf). Between 1848 and 1894 Geneva did not
|
||
# follow Bern Mean Time but kept its own local mean time.
|
||
# To represent this, an extra zone would be needed.

|
||
|
||
# From Paul Eggert (2018-10-03):
|
||
# As is usual in tzdb, Ukrainian zones use the most common English spellings.
|
||
# For example, tzdb uses Europe/Kiev, as "Kiev" is the most common spelling in
|
||
# English for Ukraine's capital, even though it is certainly wrong as a
|
||
# transliteration of the Ukrainian "Київ". This is similar to tzdb's use of
|
||
# Europe/Prague, which is certainly wrong as a transliteration of the Czech
|
||
# "Praha". ("Kiev" came from old Slavic via Russian to English, and "Prague"
|
||
# came from old Slavic via French to English, so the two cases have something
|
||
# in common.) Admittedly English-language spelling of Ukrainian names is
|
||
# controversial, and some day "Kyiv" may become substantially more popular in
|
||
# English; in the meantime, stick with the traditional English "Kiev" as that
|
||
# means less disruption for our users.
|
||
#
|
||
# Anyway, none of the common English-language spellings (Kiev, Kyiv, Kieff,
|
||
# Kijeff, Kijev, Kiyef, Kiyeff) do justice to the common pronunciation in
|
||
# Ukrainian, namely [ˈkɪjiu̯] (IPA). This pronunciation has nothing like an
|
||
# English "v" or "f", and instead trails off with what an English-speaker
|
||
# would call a demure "oo" sound, and it would would be better anglicized as
|
||
# "Kuiyu". Here's a sound file, if you would like to do as the Kuiyuvians do:

# One source shows that Bulgaria, Cyprus, Finland, and Greece observe DST from
|
||
# the last Sunday in March to the last Sunday in September in 1986.
|
||
# The source shows Romania changing a day later than everybody else.
|
||

|
||
# According to Bernard Sieloff's source, Poland is in the MET time zone but
|
||
# uses the WE DST rules. The Western USSR uses EET+1 and ME DST rules.
|
||
# Bernard Sieloff's source claims Romania switches on the same day, but at
|
||
# 00:00 standard time (i.e., 01:00 DST). It also claims that Turkey
|
||
# switches on the same day, but switches on at 01:00 standard time
|
||
# and off at 00:00 standard time (i.e., 01:00 DST)

# ...the European time rules are...standardized since 1981, when
|
||
# most European countries started DST. Before that year, only
|
||
# a few countries (UK, France, Italy) had DST, each according
|
||
# to own national rules. In 1981, however, DST started on
|
||
# 'Apr firstSun', and not on 'Mar lastSun' as in the following
|
||
# years...
|
||
# But also since 1981 there are some more national exceptions
|
||
# than listed in 'europe': Switzerland, for example, joined DST
|
||
# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
|
||
# lastSun' in 1981 - I don't know how they handle now.
|
||
#
|
||
# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
|
||
# Soviet Union (as far as I know).

|

# The information from Tom Hofmann is (as far as I know) not entirely correct.
|
||
# After a request from chongo at amdahl I tried to retrieve all information
|
||
# about DST in Europe. I was able to find all from about 1969.
|
||
#
|
||
# ...standardization on DST in Europe started in about 1977 with switches on
|
||
# first Sunday in April and last Sunday in September...
|
||
# In 1981 UK joined Europe insofar that
|
||
# the starting day for both shifted to last Sunday in March. And from 1982
|
||
# the whole of Europe used DST, with switch dates April 1 and October 1 in
|
||
# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
|
||
# dates...
|
||
#
|
||
# It should also be remembered that time-zones are not constants; e.g.
|
||
# Portugal switched in 1976 from MET (or CET) to WET with DST...
|
||
# Note also that though there were rules for switch dates not
|
||
# all countries abided to these dates, and many individual deviations
|
||
# occurred, though not since 1982 I believe. Another note: it is always
|
||
# assumed that DST is 1 hour ahead of normal time, this need not be the
|
||
# case; at least in the Netherlands there have been times when DST was 2 hours
|
||
# in advance of normal time.
