Release 2022b - 2022-08-10 15:38:32 -0700
|
||||
|
||||
Briefly:
|
||||
Chile's DST is delayed by a week in September 2022.
|
||||
Iran no longer observes DST after 2022.
|
||||
Rename Europe/Kiev to Europe/Kyiv.
|
||||
New zic -R option
|
||||
Vanguard form now uses %z.
|
||||
Finish moving duplicate-since-1970 zones to 'backzone'.
|
||||
New build option PACKRATLIST
|
||||
New tailored_tarballs target, replacing rearguard_tarballs
|
||||
|
||||
Changes to future timestamps
|
||||
|
||||
Chile's 2022 DST start is delayed from September 4 to September 11.
|
||||
(Thanks to Juan Correa.)
|
||||
|
||||
Iran plans to stop observing DST permanently, after it falls back
|
||||
on 2022-09-21. (Thanks to Ali Mirjamali.)
|
||||
|
||||
Changes to past timestamps
|
||||
|
||||
Finish moving to 'backzone' the location-based zones whose
|
||||
timestamps since 1970 are duplicates; adjust links accordingly.
|
||||
This change ordinarily affects only pre-1970 timestamps, and with
|
||||
the new PACKRATLIST option it does not affect any timestamps.
|
||||
In this round the affected zones are Antarctica/Vostok,
|
||||
Asia/Brunei, Asia/Kuala_Lumpur, Atlantic/Reykjavik,
|
||||
Europe/Amsterdam, Europe/Copenhagen, Europe/Luxembourg,
|
||||
Europe/Monaco, Europe/Oslo, Europe/Stockholm, Indian/Christmas,
|
||||
Indian/Cocos, Indian/Kerguelen, Indian/Mahe, Indian/Reunion,
|
||||
Pacific/Chuuk, Pacific/Funafuti, Pacific/Majuro, Pacific/Pohnpei,
|
||||
Pacific/Wake and Pacific/Wallis, and the affected links are

From fall 1994 through fall 1995, Shanks wrote that Crimea's
|
||||
DST transitions were at 02:00 standard time, not at 00:00.
|
||||
(Thanks to Michael Deckers.)
|
||||
|
||||
Iran adopted standard time in 1935, not 1946. In 1977 it observed
|
||||
DST from 03-21 23:00 to 10-20 24:00; its 1978 transitions were on
|
||||
03-24 and 08-05, not 03-20 and 10-20; and its spring 1979
|
||||
transition was on 05-27, not 03-21.
|
||||
(Thanks to Roozbeh Pournader and Francis Santoni.)
|
||||
|
||||
Chile's observance of -04 from 1946-08-29 through 1947-03-31 was
|
||||
considered DST, not standard time. Santiago and environs had moved
|
||||
their clocks back to rejoin the rest of mainland Chile; put this
|
||||
change at the end of 1946-08-28. (Thanks to Michael Deckers.)
|
||||
|
||||
Some old, small clock transitions have been removed, as people at
|
||||
the time did not change their clocks. This affects Asia/Hong_Kong
|
||||
in 1904, Asia/Ho_Chi_Minh in 1906, and Europe/Dublin in 1880.
|
||||
|
||||
Changes to zone name
|
||||
|
||||
Rename Europe/Kiev to Europe/Kyiv, as "Kyiv" is more common in
|
||||
English now. Spelling of other names in Ukraine has not yet
|
||||
demonstrably changed in common English practice so for now these
|
||||
names retain old spellings, as in other countries (e.g.,
|
||||
Europe/Prague not "Praha", and Europe/Sofia not "Sofiya").
|
||||
|
||||
Changes to code
|
||||
|
||||
zic has a new option '-R @N' to output explicit transitions < N.
|
||||
(Need suggested by Almaz Mingaleev.)
|
||||
|
||||
'zic -r @N' no longer outputs bad data when N < first transition.
|
||||
(Problem introduced in 2021d and reported by Peter Krefting.)
|
||||
|
||||
zic now checks its input for NUL bytes and unterminated lines, and
|
||||
now supports input line lengths up to 2048 (not 512) bytes.
|
||||
|
||||
gmtime and related code now use the abbreviation "UTC" not "GMT".
|
||||
POSIX is being revised to require this.
|
||||
|
||||
When tzset and related functions set vestigial static variables
|
||||
like tzname, they now prefer specified timestamps to unspecified ones.
|
||||
(Problem reported by Almaz Mingaleev.)
|
||||
|
||||
zic no longer complains "can't determine time zone abbreviation to
|
||||
use just after until time" when a transition to a new standard
|
||||
time occurs simultanously with the first DST fallback transition.
|
||||
|
||||
Changes to build procedure
|
||||
|
||||
Source data in vanguard form now uses the %z notation, introduced
|
||||
in release 2015f. For example, for America/Sao_Paulo vanguard
|
||||
form contains the zone continuation line "-3:00 Brazil %z", which
|
||||
is simpler and more reliable than the line "-3:00 Brazil -03/-02"
|
||||
used in main and rearguard forms. The plan is for the main form
|
||||
to use %z eventually; in the meantime maintainers of zi parsers
|
||||
are encouraged to test the parsers on vanguard.zi.
|
||||
|
||||
The Makefile has a new PACKRATLIST option to select a subset of
|
||||
'backzone'. For example, 'make PACKRATDATA=backzone
|
||||
PACKRATLIST=zone.tab' now generates TZif files identical to those
|
||||
of the global-tz project.
|
||||
|
||||
The Makefile has a new tailored_tarballs target for generating
|
||||
special-purpose tarballs. It generalizes and replaces the
|
||||
rearguard_tarballs target and related targets and macros, which
|
||||
are now obsolescent.
|
||||
|
||||
'make install' now defaults LOCALTIME to Factory not GMT,
|
||||
which means the default abbreviation is now "-00" not "GMT".
|
||||
|
||||
Remove the posix_packrat target, marked obsolescent in 2016a.

# "Circular on Matching the Hours of Governmental and Official Circles
|

# in Provinces
|
||||
# Approved 1314/03/22 [=1935-06-13]
|
||||
# According to the ruling of the Honorable Cabinet, it is ordered that from
|
||||
# now on in all internal provinces of the country, governmental and official
|
||||
# circles set their time to match Tehran time (three hours and half before
|
||||
# Greenwich)....
|
||||
#
|
||||
# I still haven't found out when Tehran itself switched to +03:30....
|
||||
#
|
||||
# From Paul Eggert (2022-06-05):
|
||||
# Although the above says Tehran was at +03:30 before 1935-06-13, we don't
|
||||
# know when it switched to +03:30. For now, use 1935-06-13 as the switch date.
|
||||
# Although most likely wrong, we have no better info.
|
||||
|
||||
# From Roozbeh Pournader (2022-06-01):
|
||||
# This is from Kayhan newspaper, one of the major Iranian newspapers, from
|
||||
# March 20, 1978, page 2:
|
||||
#
|
||||
# "Pull the clocks 60 minutes forward
|
||||
# As we informed before, from the fourth day of the month Farvardin of the
|
||||
# new year [=1978-03-24], clocks will be pulled forward, and people's daily
|
||||
# work and life program will start one hour earlier than the current program.
|
||||
# On the 1st day of the month Farvardin of this year [=1977-03-21], they had
|
||||
# pulled the clocks forward by one hour, but in the month of Mehr
|
||||
# [=1977-09-23], the clocks were pulled back by 30 minutes.
|
||||
# In this way, from the 4th day of the month Farvardin, clocks will be ahead
|
||||
# of the previous years by one hour and a half.
|
||||
# According to the new program, during the night of 4th of Farvardin, when
|
||||
# the midnight, meaning 24 o'clock is announced, the hands of the clock must
|
||||
# be pulled forward by one hour and thus consider midnight 1 o'clock in the
|
||||
# forenoon."
|
||||
#
|
||||
# This implies that in September 1977, when the daylight savings time was
|
||||
# done with, Iran didn't go back to +03:30, but immediately to +04:00.
|
||||
#
|
||||
#
|
||||
# This is from the major Iranian newspaper Ettela'at, dated [1978-08-03]...,
|
||||
# page 32. It looks like they decided to get the clocks back to +4:00
|
||||
# just in time for Ramadan that year:
|
||||
#
|
||||
# "Tomorrow Night, Pull the Clocks Back by One Hour
|
||||
# At 1 o'clock in the forenoon of Saturday 14 Mordad [=1978-08-05], the
|
||||
# clocks will be pulled one hour back and instead of 1 o'clock in the
|
||||
# forenoon, Radio Iran will announce 24 o'clock.
|
||||
# This decision was made in the Cabinet of Ministers meeting of 25 Tir
|
||||
# [=1978-07-16], [...]
|
||||
# At the beginning of the year 2537 [=March 1978: Iran was using a different
|
||||
# year number for a few years then, based on the Coronation of Cyrus the
|
||||
# Great], the country's official time was pulled forward by one hour and now
|
||||
# the official time is one hour and a half ahead compared to last year,
|
||||
# because in Farvardin of last year [=March 1977], the official time was
|
||||
# pulled forward one hour and this continued until the second half of last
|
||||
# year [=September 1977] until in the second half of last year the official
|
||||
# time was pulled back half an hour and that half hour still remains."
|
||||
#
|
||||
# This matches the time of the true noon published in the newspapers, as they
|
||||
# clearly go from +05:00 to +04:00 after that date (which happened during a
|
||||
# long weekend in Iran).
|
||||

|

# https://www.jstor.org/stable/178704
|
||||
# Here's the quotes from the paper:
|
||||
# 1. '"Iran's official time keeper moved the clock one hour forward as from
|
||||
# March 22, 1977 (Farvardin 2, 2536) to make maximum use of daylight and save
|
||||
# in energy consumption. Thus Iran joined such other countries as Britain in
|
||||
# observing what is known as 'daylight saving.' The proposal was originally
|
||||
# put forward by the Ministry of Energy, in no way having any influence on
|
||||
# observing religious ceremonies. Moving time one hour forward in summer
|
||||
# means that at 11:00 o'clock on March 21, the official time was set as
|
||||
# midnight March 22. Then September 24 will actually begin one hour later
|
||||
# than the end of September 23 [...]." Iran's time base thus continued to be
|
||||
# Greenwich Mean Time plus three and one-half hours (plus four and one-half
|
||||
# hours in summer).'

|
||||
#
|
||||
# 2. "After the fall of the shah, the revolutionary government returned to
|
||||
# daylight-saving time (DST) on 26 May 1979."
|
||||
#
|
||||
# This seems to have been announced just one day in advance, on 25 May 1979.
|
||||
#
|
||||
# The change in 1977 clearly seems to be the first daylight savings effort in
|
||||
# Iran. But the article doesn't mention what happened in 1978 (which was
|
||||
# still during the shah's government), or how things continued in 1979
|

# onwards (which was during the Islamic Republic).

# what they had to say about time there:
|

# "in the US Camp (East Camp) we have been on New Zealand (McMurdo)

# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
|

# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead

# 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

# "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

#
|

# (1993-12-10):
|

# I have a reference from the Oxford Icelandic-English dictionary for the

# 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"

# Netherlands
|

|

# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
|
||||
# but for other purposes the Netherlands used Amsterdam mean time.
|
||||
|
||||
# However, Robert H. van Gent writes (2001-04-01):
|
||||
# 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.

# Sweden
|

|

# 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
|
||||
# Parliament beginning with 1985 - the laws regulating 1980/1984 are

# (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 Reykjavík 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"

# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
|
||||
# but for other purposes the Netherlands used Amsterdam mean time.
|
||||
|
||||
# However, Robert H. van Gent writes (2001-04-01):
|
||||
# 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.
|

# 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".

# English for Ukraine's capital. Although tzdb's former name was Europe/Kiev,

# "Kyiv" is now more common due to widespread reporting of the current conflict.
