# The UK and its colonies adopted the Gregorian calendar on 1752-09-14.
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (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 deg. 28' 30" N, 0 deg. 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 <eggert@twinsun.com> (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);
|
|
# it was popularized in 1840 by Capt. Basil Hall, RN (1788-1844),
|
|
# famed explorer and former Commissioner for Longitude.
|
|
# 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 Sep 22 the
|
|
# Railway Clearing House, an industry standards body, recommended that GMT be
|
|
# adopted at all stations; the January 1848 Bradshaw's lists most major
|
|
# railways as using GMT. By 1855 the vast majority of public
|
|
# clocks in Britain were set to GMT (though some, like the Great Clock
|
|
# in 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 Aug 2.
|
|
#
|
|
# In the tables below, we condense this complicated story into a single
|
|
# transition date for London, namely 1847 Sep 22. We don't know as much
|
|
# about Dublin, so we use 1880 Aug 2, the legal transition time.
|
|
|
|
# From Paul Eggert (1996-06-12):
|
|
# Summer Time was first seriously proposed by William Willett (1857-1915),
|
|
# a London builder who circulated a pamphlet ``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.
|
|
# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
|
|
|
|
# From Paul Eggert (1996-09-03):
|
|
# 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''.
|
|
|
|
# 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.

|
|
# From: Jonathan Leffler <nih-csl!uunet!mcvax!sphinx.co.uk!john>
|
|
# [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 Peter Ilieve <peter@memex.co.uk> (1993-09-03):
|
|
#
|
|
# Our Government...couldn't...make a decision after the 1989 consultation
|
|
# exercise about the UK changing its timezone so it just let things drift
|
|
# (different from deciding to keep the status quo). According to the
|
|
# Summer Time Order 1992 (SI 1992/1729) the dates of Summer Time for 1993
|
|
# and 1994 are:
|
|
# Start End
|
|
# 1993 28 March 24 October
|
|
# 1994 27 March 23 October
|
|
# All start and end times are at 01:00 GMT.
|
|
#
|
|
# There [was] an error in your tables for the start and end times prior to 1981.
|
|
# The UK always used to change at 02:00 GMT. In 1981 it changed to 01:00 GMT
|
|
# as a part of EC harmonisation and has remained at that time since.
|
|
#
|
|
# I have found the default algorithm for UK Summer Time, it is in the
|
|
# Summer Time Act 1972. Section 1 states that in the absence of an Order
|
|
# in Council Summer Time starts at 02:00 GMT on the morning of the day
|
|
# after the third Saturday in March, unless that day is Easter Day, in
|
|
# which case it is the morning of the day after the second Saturday.
|
|
# It ends at 02:00 GMT on the morning of the day after the fourth Saturday
|
|
# in October. (All the redundant `morning of the day ...' is in the Act.)
|
|
# This is only of passing interest now as it will always be overridden by
|
|
# an Order in Council (a Statutory Instrument, the SI thing mentioned above)
|
|
# to specify the EC specified dates.
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1993-10-18):
|
|
#
|
|
# My contact in the Ministry of Defence Public Relations department
|
|
# accepted the challenge of looking into this and produced the following,
|
|
# from Hansard (the official record of the UK Parliament), Oral Answers,
|
|
# 1 March 1945, cols 1559--60:
|
|
#
|
|
# `58. Major Sir Goronwy Owen asked the Secretary of State for the Home
|
|
# Department if he is now able to state the Government's proposals
|
|
# regarding double summer time.
|
|
#
|
|
# [two other similar questions omitted]
|
|
#
|
|
# Mr. H. Morrison: The Government, in reviewing the matter, have
|
|
# considered, [...] the conclusion has been reached that the adoption of
|
|
# double summer time from the beginning of April is essential to the
|
|
# maintenance of the war effort. [...] As 1st April is Easter Sunday,
|
|
# when very early services are held in many churches, it is proposed that
|
|
# double summer time shall start not in the night preceding Easter
|
|
# Sunday, but in the night of Sunday- Monday so that it will operate from
|
|
# Monday, 2nd April.'
|
|
|
|
# From Chris Carrier <72157.3334@CompuServe.COM> (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."

|
|
# > Rule GB-Eire 1981 max - Oct Sun>=23 1:00s 0 GMT
|
|
#
|
|
# The ending rule here doesn't match the EC rules, which specify the fourth
|
|
# Sunday in October for the UK and Eire. The `fourth Sunday' rule wasn't
|
|
# followed in 1989, but then the sixth EC directive wasn't in force then
|
|
# and I don't know what previous ones said. 1995 is the next year with
|
|
# the 4th Sun on 22 Oct, but that year isn't covered by the UK Summer Time
|
|
# Order or the sixth EC directive. Your Oct Sun>=23 rule matches history
|
|
# and with things only announced for 2 years or so in advance who knows
|
|
# what will happen.
|
|
#
|
|
# There are renewed rumours that the Government here will make another
|
|
# attempt at resolving this issue, which is what prompted me to start
|
|
# asking the Home Office and the EC about it again. The EC categorically
|
|
# state they are not asking anybody to change timezone, they only want
|
|
# common start/end dates. The UK Govt. seem to want to change our zone
|
|
# and blame the resulting fuss on the EC. Me, I think we should scrap
|
|
# summer time completely, noon is when the Sun is overhead, and that should
|
|
# be the end of it.
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1993-10-22):
|
|
#
|
|
# I now have the text of the Summer Time Act 1916, the granddaddy of them all.
|
|
# It is headed: `An Act to provide for the Time in Great Britain and Ireland
|
|
# being in advance of Greenwich and Dublin mean time respectively in the
|
|
# summer months'.
|
|
#
|
|
# It specifies 21 May and 1 October for 1916 (both at 02:00 GMT) and whatever
|
|
# dates an Order in Council may specify for subsequent years.
|
|
#
|
|
# Section 4 states: `This act shall apply to Ireland in like manner as it
|
|
# applies to Great Britain, with the substitution however of references
|
|
# to Dublin mean time for references to Greenwich mean time.'
|
|
#
|
|
# Lorna, my learned legal friend who supplied it, also offers this quote
|
|
# from Halsbury's Statutes on the extent of Acts:
|
|
#
|
|
# `An Act of the United Kingdom Parliament is to be construed prima facie
|
|
# to apply to the whole of the United Kingdom and not to any place outside.
|
|
# [...] The expression "United Kingdom" for this purpose includes (since
|
|
# 1922) Great Britain (ie. England, Wales and Scotland) and Northern Ireland,
|
|
# but it does not include the Channel Islands or the Isle of Man.'
|
|
#
|
|
# She goes on to say the seminal event of 1922 was the establishment of
|
|
# the Irish Free State, now called Eire.
|
|
#
|
|
# The Act doesn't say anything about Wales (or Scotland) so I would assert
|
|
# that Shanks is wrong here. I would like to know why he thinks Wales
|
|
# was different.
|
|
#
|
|
# It also confirms the fact that Ireland followed Dublin time back then,
|
|
# and 25 minutes behind Greenwich, as Shanks has it, would be correct.
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1993-10-28):
|
|
#
|
|
# I now have before me, thanks to my learned legal friend Lorna, the text of
|
|
# the Time (Ireland) Act 1916.
|
|
#
|
|
# It says that as from 2 AM Dublin Mean Time on 1 October 1916 the time
|
|
# for general purposes in Ireland shall be the same as the rest of Great
|
|
# Britain (ie. GMT with the Summer Time periods specified by the Summer Time
|
|
# Act 1916).... As Ireland was behind GMT/BST at 02:00 DMT on 1 Oct GB would
|
|
# have already put the clocks back. Using DST as Dublin Summer Time the
|
|
# sequence would have been:
|
|
# Dublin London
|
|
# 02:34 DST 02:59 BST
|
|
# 02:35 DST 02:00 GMT
|
|
# 02:59 DST 02:24 GMT
|
|
# 02:25 GMT 02:25 GMT
|
|
# with the transition 03:00 DST -> 02:00 DMT -> 02:25 GMT all at once.
|
|
#
|
|
# In a table of repeals in the Schedule to the Act it mentions the
|
|
# Statutes (Definition of Time) Act 1880. This is presumably the source
|
|
# of the 1880 date in Shanks. The little bit of it that is repealed
|
|
# also refers solely to Ireland and Dublin Mean Time.
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1993-10-29):
|
|
#
|
|
# My case is that, with the sole exception of Ireland in 1916 using Dublin
|
|
# Mean Time, Summer Time has been uniform throughout the United Kingdom
|
|
# ever since it first started in 1916.
|
|
#
|
|
# The United Kingdom is England, Wales and Scotland plus all of Ireland from
|
|
# 1916 up to and including 1921, or plus Northern Ireland from 1922 to date.
|
|
#
|
|
# The dates used are those specified in the table in Summer Time: A Consultation
|
|
# Document (Cm 722, 1989) that are now included in the europe file, with a
|
|
# change to a single date, the start in 1924. I made a typo in my 1989 mail
|
|
# and the table itself is also wrong. The correct date is 13 April.
|
|
# The times were 02:00 GMT up to and including 1980, 01:00 GMT from 1981 on,
|
|
# except for wartime double summer time.
|
|
#
|
|
# As evidence I would cite:
|
|
#
|
|
# - The Summer Time Act, 1916.
|
|
#
|
|
# This specifically states that it applies to Ireland, specifies dates of
|
|
# 21 May and 1 October and times of 02:00, and says that in Ireland the
|
|
# times relate to Dublin mean time. It specifies an offset of 1 hour.
|
|
#
|
|
# - The Time (Ireland) Act, 1916
|
|
#
|
|
# This abolishes Dublin mean time on 02:00 DMT 1 October 1916.
|
|
# It repeals that section of the Statutes (Definition of Time) Act, 1880
|
|
# that specifies DMT. It is therefore a safe bet that DMT existed at least
|
|
# from 1880 and was the only alternative standard time in the UK.
|
|
#
|
|
# - The Summer Time Act, 1922
|
|
#
|
|
# This specifies an offset of 1 hour and dates of the day after the third
|
|
# Saturday in April, unless that be Easter, in which case it is the day after
|
|
# the second Saturday, and the day after the third Saturday in September.
|
|
# The time is 02:00 GMT. It applied in 1922 and 1923, and longer if Parliament
|
|
# so approved.
|
|
#
|
|
# It specifically states that it applies to Northern Ireland, the Channel
|
|
# Islands, and the Isle of Man.
|
|
#
|
|
# - The Summer Time Act, 1925
|
|
#
|
|
# This makes the 1922 Act permanent, with a change to the end date to the
|
|
# day after the first Saturday in October. It says nothing about extent,
|
|
# so that part of the 1922 Act will still apply.
|
|
#
|
|
# - The Defence (Summer Time) Regulations, 1939, SR&O 1939 No. 1379
|
|
# [SR&O == Statutory Regulation and Order]
|
|
#
|
|
# These were made under the Emergency Powers (Defence) Act, 1939.
|
|
# It changes the end date to be the day after the third Saturday in November.
|
|
# It makes consequential changes to some vehicle lighting legislation,
|
|
# which includes the Motor Vehicles and Road Traffic (Northern Ireland) Act,
|
|
# 1934, so it seems clear it applies in Northern Ireland.

# the first Saturday in May and ending at 01:00 GMT on the day after the
|
|
# second Saturday in August, offset another hour from normal summer time,
|
|
# which continues throughout the rest of the year. It goes on a lot about
|
|
# consequential changes to agricultural wages legislation, and says in part
|
|
# `... and in its application to Northern Ireland have effect as
|
|
# if for the references to the Agricultural Wages (Regulation) Acts, 1924 and
|
|
# 1940, there were substituted references to the Agricultural Wages (Regulation)
|
|
# Acts (Northern Ireland), 1939 and 1940, ...'. It also has a similar section

# This is an Act of Tynwald (the Isle of Man Parliament) that said that
|
|
# henceforth Manx time would be the same as the time in Great Britain.
|
|
#
|
|
# - The Summer Time Act, 1972
|
|
#
|
|
# This specified a reversion to normal summer time behaviour with a start
|
|
# date of the day after the third Saturday in March, unless that is Easter,
|
|
# when it is the day after the second Saturday, and an end date of the day
|
|
# after the fourth Saturday in October. Times are at 02:00 GMT, offset is
|
|
# 1 hour.
|
|
#
|
|
# It has the same wording about extent as the British Standard Time Act, 1968,
|
|
# applying to Northern Ireland unconditionally and to Jersey, Guernsey and the
|
|
# Isle of Man if they don't do something about it.
|
|
#
|
|
# (I am missing various Summer Time Orders that modified the 1972 Act to
|
|
# harmonise with the EC since 1981. The major change is that the time changes
|
|
# to 01:00 GMT.)
|
|
#
|
|
# - The Summer Time Order, 1992, SI 1992/1729 [SI == Statutory Instrument]
|
|
#
|
|
# This specifies dates of:
|
|
# Start End
|
|
# 1993 28 March 24 October
|
|
# 1994 27 March 23 October
|
|
# All start and end times are at 01:00 GMT....

#
|
|
# - Some text on the extent of Acts, from Halsbury's Statutes
|
|
#
|
|
# `An Act of the United Kingdom Parliament is to be construed prima facie
|
|
# to apply to the whole of the United Kingdom and not to any place outside.
|
|
# [...] The expression "United Kingdom" for this purpose includes (since
|
|
# 1922) Great Britain (ie. England, Wales and Scotland) and Northern Ireland,
|
|
# but it does not include the Channel Islands or the Isle of Man.'
|
|
#
|
|
# So, many of these measures specifically include Northern Ireland,
|
|
# the Channel Islands and the Isle of Man. None of them exclude any
|
|
# part of the UK. The default interpretation of Acts is that they apply
|
|
# throughout the UK.
|
|
#
|
|
# With that, I rest my case Milud :-)
|
|
#
|
|
# Thanks are due to my learned legal friend Lorna Montgomerie, who dug out
|
|
# the dusty old statutes, and to Melanie Allison of the Ministry of Defence,
|
|
# who provided the wartime regulations and a snippet of Hansard explaining
|
|
# why double summer time started on a Monday in 1945 (it was Easter).
|
|
|
|
# From Peter Ilieve <peter@aldie.co.uk> (1996-05-29):
|
|
# I have now got a copy of the British Standard Time Act 1968.
|
|
# It says (S4(2)) that it expires at 02:00 GMT on 31 October 1971 unless
|
|
# an Order in Council was passed in Parliament to make the Act permanent.
|
|
# No Order was passed, so 02:00 1971-10-31 it is...
|
|
#
|
|
# Interestingly, it says baldly `This Act shall come into force on
|
|
# 27 October 1968', without giving a time. As S1 of the Act merely
|
|
# stated that `The time for general purposes in the United Kingdom
|
|
# (to be known as British standard time) shall be one hour in
|
|
# advance of Greenwich mean time throughout the year; ...' you could
|
|
# possibly argue that the start time of BStandardT was 00:00 1968-10-27,
|
|
# especially as the Act repealed the Summer Time Acts 1916--1947 in toto,
|
|
# thereby destroying the authority of the Summer Time Order specifying
|
|
# summer time in 1968....
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1993-11-18)
|
|
#
|
|
# Here is a revised version of my tabrules file for the perl script I sent
|
|
# before. I have personally verified the various Orders back to 1953 and
|
|
# all the Acts.
|
|
#
|
|
# There are no changes to the dates we already have.
|
|
#
|
|
# My doubt about an early start in 1967 on 18 Feb was misplaced, the Order
|
|
# does say 18 Feb. This is an interesting case as the first Order gave a
|
|
# different date of 7 April 1967 for the Isle of Man but this was changed
|
|
# before it came into effect by another Order for the Isle of Man alone.
|
|
#
|
|
# I don't think I will be able to find any more of the earlier Orders.
|
|
# The annual volumes for 1949--52 do not contain the various Summer Time
|
|
# Orders. They therefore don't appear in the index. They rate a mention in
|
|
# italics in the numerical list at the start but that is all.
|
|
# I think what happens is that the annual volume is produced well after the
|
|
# end of the year in question, by which time the Summer Time Order is spent.
|
|
# They assume that nobody would ever be stupid enough to want to see it
|
|
# again so they leave it out.
|
|
#
|
|
# It might be a good idea to put this table, or the output of tabscript
|
|
# showing all the moves because of Easter, in the europe file comments in
|
|
# place of my old transcription of the Green Paper table [the UK Government
|
|
# paper "Summer Time: A Consultation Document" (HMSO Cm722 June 1989)].

|
|
# The final piece of the legislative jigsaw for summer time in the UK for
|
|
# 1995-97 is now in place. The Summer Time Order 1994 (SI 1994/2798)
|
|
# came into force on 16 November. It restates the dates from the EC
|
|
# seventh Summer Time Directive....
|
|
#
|
|
# From Peter Ilieve <peter@aldie.co.uk> (1996-04-20):
|
|
# Proposals for the eighth directive were supposed to have been produced
|
|
# by the Commission by 1 Jan 96. They have not yet appeared (I asked just
|
|
# before Easter).
|
|
|
|
# From Peter Ilieve <peter@memex.co.uk> (1994-03-28):
|
|
# The [GB-Eire] end date of 22 October [1995] conflicts with your current rule
|
|
# of Oct Sun>=23, and the historical UK formula of Sun after 4th Sat.
|
|
# The last time 4th Sun and Sun after 4th Sat differed was in 1989,
|
|
# when 29 October was used. That year was covered by a UK Summer Time Order
|
|
# for only a single year and it looks as though there was a matching 4th EC
|
|
# directive for just this year. I don't have the text of the 5th EC
|
|
# directive (for 1990--92) but my guess would be it said 4th Sun.
|
|
# To maintain strict historical accuracy you could start a new UK ending rule
|
|
# of Oct Sun>=22 in 1990.
|
|
|
|
# From Paul Eggert <eggert@twinsun.com> (1996-06-12):
|
|
#
|
|
# As Ilieve remarks, the date `20 April 1924' in the table of ``Summer Time: A
|
|
# Consultation Document'' (Cm 722, 1989) table is a transcription error;
|
|
# 20 April was an Easter Sunday. Shanks has 13 April, the correct date.
|
|
# Also, the table is not quite right for 1925 through 1938; the correct rules
|
|
# (which Shanks uses) are given in the Summer Time Acts of 1922 and 1925.
|
|
# Shanks and the UK Government paper disagree about the Apr 1956 transition;
|
|
# since we have no other data, and since Shanks was correct in the other
|
|
# points of disagreement about London, we'll believe Shanks for now.
|
|
# Also, for lack of other data, we'll follow Shanks for Eire in 1940-1948.
|
|
#
|
|
# Given Peter Ilieve's comments, the following claims by Shanks are incorrect:
|
|
# * Wales did not switch from GMT to daylight savings 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 savings 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).
|
|
#
|
|
# The following claims by Shanks are possible though doubtful;
|
|
# we'll ignore them for now.
|
|
# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
|
|
# to daylight savings time until 1921 Apr 3, when they began to
|
|
# conform with Great Britain.
|
|
# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
|
|
#
|
|
#
|
|
# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
|
|
|
|
# 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 # 94/21/EC.

# Iceland

|
#
|
|
# From Adam David <adam@veda.is> (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 (???).
|
|
#
|
|
# From Paul Eggert <eggert@twinsun.com> (1993-12-09):
|
|
# The Iceland Almanak, Shanks and Whitman disagree on many points.
|
|
# We go with the Almanak, except for one claim from Shanks, namely that
|
|
# Reykavik was -1:28 from 1837 to 1908, local mean time before that.

# From Chris Carrier <72157.3334@CompuServe.COM> (1996-12-02):
|
|
# On 1929-10-01 the Soviet Union instituted an ``Eternal Calendar''
|
|
# with 30-day months plus 5 holidays, with a 5-day week.
|
|
# On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the
|
|
# Gregorian calendar while retaining the 6-day week; on 1940-06-27 it
|
|
# reverted to the 7-day week. With the 6-day week the usual days
|
|
# off were the 6th, 12th, 18th, 24th and 30th of the month.
|

# (Source: Evitiar Zerubavel, _The Seven Day Circle_)

#
|

|
|
# Except for Moscow after 1919-07-01, I invented the time zone abbreviations,
|
|
# and (unless otherwise specified) guessed what happened after 1991.
|
|
# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,

#
|
|
# From Andrey A. Chernov <ache@nagual.ru> (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
|
|
# (used mainly for mail), and MSK/MSD was actively used there.
|
|
#
|
|
# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):

# According to a friend of mine who rode the Trans-Siberian Railroad from

# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...

#
|
|
# In 1700, Denmark made the transition from Julian to Gregorian. Sweden
|
|
# decided to *start* a transition in 1700 as well, but rather than have one of
|
|
# those unsightly calendar gaps :-), they simply decreed that the next leap
|
|
# year after 1696 would be in 1744 -- putting the whole country on a calendar
|
|
# different from both Julian and Gregorian for a period of 40 years.
|
|
#
|
|
# However, in 1704 something went wrong and the plan was not carried through;
|
|
# they did, after all, have a leap year that year. And one in 1708. In 1712
|
|
# they gave it up and went back to Julian, putting 30 days in February that
|
|
# year!...
|
|
#
|
|
# Then in 1753, Sweden made the transition to Gregorian in the usual manner,
|
|
# getting there only 13 years behind the original schedule.
|
|
#
|
|
# (A previous posting of this story was challenged, and Swedish readers
|
|
# produced the following references to support it: "Tiderakning och historia"
|
|
# by Natanael Beckman (1924) and "Tid, en bok om tiderakning och
|
|
# kalendervasen" by Lars-Olof Lode'n (no date was given).)

|

# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep

# 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.

# Turning to Europe, I now have a copy of the `Sixth Council Directive 92/20/EEC
|
|
# of 26 March 1992 on summertime arrangements'. This only covers 1993 and
|
|
# 1994, a seventh one is in the works but I doubt that the algorithm will
|
|
# change. This says summertime starts at 01:00 GMT on the last Sunday in March
|
|
# and ends at 01:00 GMT on the last Sunday in September, except for the UK
|
|
# and Eire where it ends at 01:00 GMT on the fourth Sunday in October.
|
|
# It says the arrangements for 1995 onwards will be decided by 1 January 1994,
|
|
# but as the sixth directive was supposed to appear by 1 Jan 92 and didn't
|
|
# arrive til March I wouldn't hold your breath.
|
|
#
|
|
# The first summertime directive was adopted in 1980, although the UK didn't
|
|
# seem to use it until 1981. I suspect it would be safe to move your start
|
|
# dates for the -Eur rules back to 1981.
