|
# A good source for time zone historical data outside the U.S. is
|

# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
|
|
# San Diego: ACS Publications, Inc. (2003).
|
|
#
|
|
# Gwillim Law writes that a good source
|
|
# for recent time zone data is 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, Shanks & Pottenger is the source for
|
|
# entries through 1990, and IATA SSIM is the source for entries afterwards.
|
|
#
|
|
# Another source occasionally used is Edward W. Whitman, World Time Differences,
|
|
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which

|
# I found in the UCLA library.

|
|
# From Paul Eggert (2006-03-22):

|
# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
|
|
# in spring 1991, then to 4:00 with no DST in fall 1995, then
|
|
# readopting Russian DST in 1997. Go with Shanks & Pottenger, even

|
# when they disagree with others. Edgar Der-Danieliantz
|
|
# reported (1996-05-04) that Yerevan probably wouldn't use DST
|
|
# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
|
|
# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

# No they don't. See TIME mag, 1986-02-17 p.52. Even though

# From Luther Ma (2009-10-17):
|
|
# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
|
|
# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
|
|
# but have no need of it. All planes, trains, and schools function on
|
|
# what is called "Beijing time." When Han make an appointment in Chinese
|
|
# they implicitly use Beijing time.
|
|
#
|
|
# On the other hand, ethnic Uyghurs, who make up about half the
|
|
# population of Xinjiang, typically use "Xinjiang time" which is two
|
|
# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
|
|
# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
|
|
# local governments such as the Urumqi city government use both times in
|
|
# publications, referring to what is popularly called Xinjiang time as
|
|
# "Urumqi time." When Uyghurs make an appointment in the Uyghur language
|
|
# they almost invariably use Xinjiang time.
|
|
#
|
|
# (Their ethnic Han compatriots would typically have no clue of its
|
|
# widespread use, however, because so extremely few of them are fluent in
|
|
# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
|
|
#
|
|
# (...As with the rest of China there was a brief interval ending in 1990
|
|
# or 1991 when summer time was in use. The confusion was severe, with
|
|
# the province not having dual times but four times in use at the same
|
|
# time. Some areas remained on standard Xinjiang time or Beijing time and
|
|
# others moving their clocks ahead.)

# ...
|
|
# 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the

# Without having access to local historical records, nor the ability to legally

# Kong. [According] to the DST record from Hong Kong Observatory (actually,
|
|
# it is not [an] observatory, but the official meteorological agency of HK,

|
|
# From Paul Eggert (1994-11-19):
|

# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
|
|
# an hour recently, due to a law proposed by Zurab Murvanidze,
|
|
# an MP who went on a hunger strike for 11 days to force discussion about it!
|
|
# We have no details, but we'll guess they didn't move the clocks back in fall.
|
|
#
|
|
# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
|
|
# Instead of putting back clocks at the end of October, Georgia
|
|
# will stay on daylight savings time this winter to save energy,
|
|
# President Eduard Shevardnadze decreed Wednesday.
|
|
#
|
|
# From the BBC via Joseph S. Myers (2004-06-27):
|
|
#
|
|
# Georgia moved closer to Western Europe on Sunday... The former Soviet
|
|
# republic has changed its time zone back to that of Moscow. As a result it
|
|
# is now just four hours ahead of Greenwich Mean Time, rather than five hours
|
|
# ahead. The switch was decreed by the pro-Western president of Georgia,
|
|
# Mikhail Saakashvili, who said the change was partly prompted by the process
|
|
# of integration into Europe.
|
|
|
|
# From Teimuraz Abashidze (2005-11-07):
|
|
# Government of Georgia ... decided to NOT CHANGE daylight savings time on
|
|
# [Oct.] 30, as it was done before during last more than 10 years.
|
|
# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
|
|
# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
|
|
# about it. As far as I can find, I was told, that there is no document,
|
|
# because we just DIDN'T ISSUE document about switching to winter time....
|

# I don't know what can be done, especially knowing that some years ago our

# East Timor

# From Joao Carrascalao, brother of the former governor of East Timor, in
|
|
# <a href="http://etan.org/et99c/december/26-31/30ETMAY.htm">
|
|
# East Timor may be late for its millennium
|
|
# </a> (1999-12-26/31):
|
|
# Portugal tried to change the time forward in 1974 because the sun
|
|
# rises too early but the suggestion raised a lot of problems with the
|
|
# Timorese and I still don't think it would work today because it
|
|
# conflicts with their way of life.
|
|
|
|
# From Paul Eggert (2000-12-04):
|
|
# We don't have any record of the above attempt.
|
|
# Most likely our records are incomplete, but we have no better data.

# From Manoel de Almeida e Silva, Deputy Spokesman for the UN Secretary-General
|
|
# (2000-08-16)</a>:
|
|
# The Cabinet of the East Timor Transition Administration decided
|
|
# today to advance East Timor's time by one hour. The time change,

|
# which will be permanent, with no seasonal adjustment, will happen at

|
|
# says that Indonesia's time zones changed on 1988-01-01. Looking at some

# JohnTWB writes that Japanese forces did not surrender control in

# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and

# September 12 for the regional surrender to Mountbatten in Singapore.

|
# These would be the earliest possible times for a change.

# Iran
|
|
|
|
# From Roozbeh Pournader (2003-03-15):
|
|
# This is an English translation of what I just found (originally in Persian).
|
|
# The Gregorian dates in brackets are mine:
|
|
#
|
|
# Official Newspaper No. 13548-1370/6/25 [1991-09-16]
|
|
# No. 16760/T233 H 1370/6/10 [1991-09-01]
|
|
#
|
|
# The Rule About Change of the Official Time of the Country
|
|
#
|
|
# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
|
|
# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
|
|
# of the Country's Organization for Official and Employment Affairs,
|
|
# and referring to the law for equating the working hours of workers
|
|
# and officers in the whole country dated 1359/4/23 [1980-07-14], and
|
|
# for synchronizing the official times of the country, agreed that:
|
|
#
|
|
# The official time of the country will should move forward one hour
|
|
# at the 24[:00] hours of the first day of Farvardin and should return
|
|
# to its previous state at the 24[:00] hours of the 30th day of
|
|
# Shahrivar.
|
|
#
|
|
# First Deputy to the President - Hassan Habibi
|
|
#
|
|
# From personal experience, that agrees with what has been followed
|
|
# for at least the last 5 years. Before that, for a few years, the
|
|
# date used was the first Thursday night of Farvardin and the last
|
|
# Thursday night of Shahrivar, but I can't give exact dates....
|
|
# I have also changed the abbreviations to what is considered correct
|
|
# here in Iran, IRST for regular time and IRDT for daylight saving time.
|
|
#
|
|
# From Roozbeh Pournader (2005-04-05):
|
|
# The text of the Iranian law, in effect since 1925, clearly mentions
|
|
# that the true solar year is the measure, and there is no arithmetic
|
|
# leap year calculation involved. There has never been any serious
|
|
# plan to change that law....
|
|
#
|
|
# From Paul Eggert (2006-03-22):
|
|
# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
|
|
# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
|
|
# stopping after 2037 when 32-bit time_t's overflow.
|
|
# That cal-persia used Birashk's approximation, which disagrees with the solar
|
|
# calendar predictions for the year 2025, so I corrected those dates by hand.
|
|
#
|
|
# From Oscar van Vlijmen (2005-03-30), writing about future
|
|
# discrepancies between cal-persia and the Iranian calendar:
|
|
# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
|
|
# the vernal equinox and that gets so close to 12:00 some local
|
|
# Iranian time that the definition of the correct location needs to be
|
|
# known exactly, amongst other factors. 2157 is even closer:
|
|
# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
|
|
# no interpretation problem whatsoever. By the way, another instant
|
|
# in the near future where there will be a discrepancy between
|
|
# arithmetical and astronomical Iranian calendars will be in 2058:
|
|
# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
|
|
# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
|
|
# 2058-03-21 for 1 Farvardin 1437 (astronomical).
|
|
#
|
|
# From Steffen Thorsen (2006-03-22):
|
|
# Several of my users have reported that Iran will not observe DST anymore:
|
|
# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
|
|
#
|
|
# From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:
|
|
# ... the Guardian Council ... approved a law on Sunday to re-introduce
|
|
# daylight saving time ...
|
|
# http://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
|
|
#
|
|
# From Roozbeh Pournader (2007-11-05):
|
|
# This is quoted from Official Gazette of the Islamic Republic of
|
|
# Iran, Volume 63, Number 18242, dated Tuesday 1386/6/24
|
|
# [2007-10-16]. I am doing the best translation I can:...
|
|
# The official time of the country will be moved forward for one hour
|
|
# on the 24 hours of the first day of the month of Farvardin and will
|
|
# be changed back to its previous state on the 24 hours of the
|
|
# thirtieth day of Shahrivar.

#
|
|
# From Jonathan Lennox (2000-06-12):
|
|
# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
|
|
# the U.S. edition) on the Iraqi Kurds contains a paragraph:
|
|
# "The three northern provinces ... switched their clocks this spring and
|
|
# are an hour ahead of Baghdad."
|
|
#
|
|
# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
|
|
# In the past, some Kurdish nationalists, as a protest to the Iraqi
|
|
# Government, did not adhere to daylight saving time. They referred
|
|
# to daylight saving as Saddam time. But, as of today, the time zone
|
|
# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
|
|
#
|
|
# So we'll ignore the Economist's claim.
|
|
|
|
# From Steffen Thorsen (2008-03-10):
|
|
# The cabinet in Iraq abolished DST last week, according to the following

# Israel

|
|
# From Ephraim Silverberg (2001-01-11):
|
|
#
|
|
# I coined "IST/IDT" circa 1988. Until then there were three
|
|
# different abbreviations in use:
|
|
#
|
|
# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
|
|
# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
|
|
# EEST Eastern Europe Standard Time [used by almost everyone else]
|
|
#
|
|
# Since timezones should be called by country and not capital cities,
|
|
# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
|
|
# EEST was equally unacceptable. Since "zonal" was not compatible with
|
|
# any other timezone abbreviation, I felt that 'IST' was the way to go
|
|
# and, indeed, it has received almost universal acceptance in timezone
|
|
# settings in Israeli computers.
|
|
#
|
|
# In any case, I am happy to share timezone abbreviations with India,
|
|
# high on my favorite-country list (and not only because my wife's
|
|
# family is from India).

# From Ephraim Silverberg
|
|
# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
|
|
# and 2005-02-17):
|
|
|
|
# According to the Office of the Secretary General of the Ministry of
|
|
# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
|
|
# One thing is entrenched in law, however: that there must be at least 150
|
|
# days of daylight savings time annually. From 1993-1998, the change to
|
|
# daylight savings time was on a Friday morning from midnight IST to
|
|
# 1 a.m IDT; up until 1998, the change back to standard time was on a
|
|
# Saturday night from midnight daylight savings time to 11 p.m. standard
|
|
# time. 1996 is an exception to this rule where the change back to standard
|
|
# time took place on Sunday night instead of Saturday night to avoid
|
|
# conflicts with the Jewish New Year. In 1999, the change to
|
|
# daylight savings time was still on a Friday morning but from
|
|
# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
|
|
# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
|
|
# 1999 only. In the year 2000, the change to daylight savings time was
|
|
# similar to 1999, but although the change back will be on a Friday, it
|
|
# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
|
|
# changes to/from will take place at 1 a.m. old time, but now there is no
|
|
# rule as to what day of the week it will take place in as the start date
|
|
# (except in 2003) is the night after the Passover Seder (i.e. the eve
|
|
# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
|
|
# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
|
|
# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

# `9:00' and `JST' is from Guy Harris.
|
|
|
|
# From Paul Eggert (1995-03-06):
|
|
# Today's _Asahi Evening News_ (page 4) reports that Japan had
|
|
# daylight saving between 1948 and 1951, but ``the system was discontinued
|
|
# because the public believed it would lead to longer working hours.''
|
|
|
|
# From Mayumi Negishi in the 2005-08-10 Japan Times
|
|
# <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
|
|
# Occupation authorities imposed daylight-saving time on Japan on
|
|
# [1948-05-01].... But lack of prior debate and the execution of
|
|
# daylight-saving time just three days after the bill was passed generated
|
|
# deep hatred of the concept.... The Diet unceremoniously passed a bill to
|
|
# dump the unpopular system in October 1951, less than a month after the San
|
|
# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
|
|
# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
|
|
# wanted to keep it.)
|
|
|
|
# From Paul Eggert (2006-03-22):
|
|
# Shanks & Pottenger write that DST in Japan during those years was as follows:

|
|
# but the only locations using it (for birth certificates, presumably, since
|
|
# their audience is astrologers) were US military bases. For now, assume
|
|
# that for most purposes daylight-saving time was observed; otherwise, what
|
|
# would have been the point of the 1951 poll?
|
|
|
|
# From Hideyuki Suzuki (1998-11-09):
|
|
# 'Tokyo' usually stands for the former location of Tokyo Astronomical
|
|
# Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
|
|
# This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
|
|
# edited by National Astronomical Observatory of Japan....
|
|
# JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
|
|
# The law is enacted on 1886-07-07.
|
|
|
|
# From Hideyuki Suzuki (1998-11-16):
|
|
# The ordinance No. 51 (1886) established "standard time" in Japan,
|
|
# which stands for the time on E 135 degree.
|
|
# In the ordinance No. 167 (1895), "standard time" was renamed to "central
|
|
# standard time". And the same ordinance also established "western standard
|
|
# time", which stands for the time on E 120 degree.... But "western standard
|
|
# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
|
|
# 167, there is no mention regarding for what place western standard time is
|
|
# standard....
|
|
#
|
|
# I wrote "ordinance" above, but I don't know how to translate.
|
|
# In Japanese it's "chokurei", which means ordinance from emperor.
|
|
|
|
# Shanks & Pottenger claim JST in use since 1896, and that a few
|
|
# places (e.g. Ishigaki) use +0800; go with Suzuki. Guess that all

# Andrew Evtichov (1996-04-13) writes that Kazakhstan
|
|
# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
|
|
# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
|
|
# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
|
|
# IATA SSIM mentions a third time zone in Kazakhstan.
|
|
|
|
# From Paul Eggert (2006-03-22):
|
|
# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
|
|
# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
|
|
# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
|
|
# Also go with the following claims of Shanks & Pottenger:
|
|
#
|
|
# - Kazakhstan did not observe DST in 1991.
|
|
# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
|
|
# - Oral switched from +5:00 to +4:00 in spring 1989.

# </a>
|

# The Government of Kazakhstan passed a resolution March 15 abolishing

# daylight saving time citing lack of economic benefits and health

#
|
|
# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
|
|
# ... what happened was that the former Kazakhstan Eastern time zone
|
|
# was "blended" with the Central zone. Therefore, Kazakhstan now has
|
|
# two time zones, and difference between them is one hour. The zone
|
|
# closer to UTC is the former Western zone (probably still called the
|
|
# same), encompassing four provinces in the west: Aqtobe, Atyrau,
|
|
# Mangghystau, and West Kazakhstan. The other zone encompasses
|
|
# everything else.... I guess that would make Kazakhstan time zones

# From Rives McDow (2002-03-13):
|
|
# I have been advised that Pakistan has decided to adopt dst on a
|
|
# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
|
|
# and ending at 00:01 local time October 6, 2002. This is what I was
|
|
# told, but I believe that the actual time of change may be 00:00; the
|
|
# 00:01 was to make it clear which day it was on.

|
# advance the clocks by one hour on the night between the first
|
|
# Saturday and Sunday of April and revert to the original position on
|
|
# 15th October each year". This agrees with McDow's 04-07 at 00:00,
|
|
# but disagrees about the October transition, and makes it sound like
|
|
# it's not on a trial basis. Also, the "between the first Saturday

|
# transition takes place at 00:00 on the first Sunday on or after 04-02.

# Palestine
|
|
|
|
# From Amos Shapir (1998-02-15):
|
|
#
|
|
# From 1917 until 1948-05-15, all of Palestine, including the parts now
|
|
# known as the Gaza Strip and the West Bank, was under British rule.
|
|
# Therefore the rules given for Israel for that period, apply there too...
|
|
#
|
|
# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
|
|
# (except a short occupation by Israel from 1956-11 till 1957-03, but no
|
|
# time zone was affected then). It was never formally annexed to Egypt,
|
|
# though.
|
|
#
|
|
# The rest of Palestine was under Jordanian rule at that time, formally
|
|
# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
|
|
# the country's previous name of "the Hashemite Kingdom of the
|
|
# Trans-Jordan"). So the rules for Jordan for that time apply. Major
|
|
# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
|
|
# East Jerusalem.
|
|
#
|
|
# Both areas were occupied by Israel in June 1967, but not annexed (except
|
|
# for East Jerusalem). They were on Israel time since then; there might
|
|
# have been a Military Governor's order about time zones, but I'm not aware
|
|
# of any (such orders may have been issued semi-annually whenever summer
|
|
# time was in effect, but maybe the legal aspect of time was just neglected).
|
|
#
|
|
# The Palestinian Authority was established in 1993, and got hold of most
|
|
# towns in the West Bank and Gaza by 1995. I know that in order to
|
|
# demonstrate...independence, they have been switching to
|
|
# summer time and back on a different schedule than Israel's, but I don't
|
|
# know when this was started, or what algorithm is used (most likely the
|
|
# Jordanian one).
|
|
#
|
|
# To summarize, the table should probably look something like that:
|
|
#
|
|
# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-

# have one).
|

|
# From Paul Eggert (2006-03-22):
|
|
# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
|
|
# with Shapir and assume that it observed DST from 1940 through 1947,
|
|
# and that it used Jordanian rules starting in 1996.
|
|
# We don't yet need a separate entry for the West Bank, since
|
|
# the only differences between it and Gaza that we know about
|
|
# occurred before our cutoff date of 1970.
|
|
# However, as we get more information, we may need to add entries
|
|
# for parts of the West Bank as they transitioned from Israel's rules
|
|
# to Palestine's rules. If you have more info about this, please
|
|
# send it to tz@elsie.nci.nih.gov for incorporation into future editions.

#
|
|
# Despite the fact that Israel changed over to daylight savings time
|

# last week, the PLO Authority (PA) has decided not to turn its clocks

# I think the abbreviation LKT originated from the world of computers at
|
|
# the time of or subsequent to the time zone changes by SL Government
|
|
# twice in 1996 and probably SL Government or its standardization
|
|
# agencies never declared an abbreviation as a national standard.
|
|
#
|
|
# I recollect before the recent change the government annoucemments
|
|
# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
|
|
# Time and no mention was made about the abbreviation.
|
|
#
|
|
# If we look at Sri Lanka Department of Government's "Official News
|
|
# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
|
|
# use SLT as abbreviation in time stamp at the beginning of each news
|
|
# item....
|
|
#
|
|
# Within Sri Lanka I think LKT is well known among computer users and
|
|
# adminsitrators. In my opinion SLT may not be a good choice because the
|
|
# nation's largest telcom / internet operator Sri Lanka Telcom is well
|
|
# known by that abbreviation - simply as SLT (there IP domains are
|
|
# slt.lk and sltnet.lk).
|
|
#
|
|
# But if indeed our government has adopted SLT as standard abbreviation
|
|
# (that we have not known so far) then it is better that it be used for
|
|
# all computers.
|
|
|
|
# From Paul Eggert (2006-04-25):
|
|
# One possibility is that we wait for a bit for the dust to settle down
|
|
# and then see what people actually say in practice.
