|
|
# From Paul Eggert (2006-03-22):
|
|
#
|
|
# 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.
|
|
#
|
|
# A reliable and entertaining source about time zones is
|
|
# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

# 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,

# People's Republic of China. Yes, they really have only one time zone.

|
|
|
# From Bob Devine (1988-01-28):
|
|
# No they don't. See TIME mag, 1986-02-17 p.52. Even though
|
|
# China is across 4 physical time zones, before Feb 1, 1986 only the
|
|
# Peking (Bejing) time zone was recognized. Since that date, China
|
|
# has two of 'em -- Peking's and Urumqi (named after the capital of
|
|
# the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
|
|
#
|
|
# . . .I just deleted the DST table and this editor makes it too
|
|
# painful to suck in another copy.. So, here is what I have for

|
|
# has had a single time zone since 1980 May 1, observing summer DST
|
|
# from 1986 through 1991; this contradicts Devine's
|
|
# note about Time magazine, though apparently _something_ happened in 1986.

# Georgia
|
|
# 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
|
|
# DST rules where changed THREE TIMES during one month.

|
|
|
# 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 Paul Eggert (2006-03-22):
|
|
# The above comments about post-2006 transitions may become relevant again,
|
|
# if Iran ever resuscitates DST, so we'll leave the comments in.
|
|

# From Jonathan Lennox (2000-06-12):

# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in

# "The three northern provinces ... switched their clocks this spring and

|

#
|
|
# 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.

|
|
# 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 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.''
|

|

|
|
# <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):

|
|
# From Hideyuki Suzuki (1998-11-09):
|
|
# 'Tokyo' usually stands for the former location of Tokyo Astronomical

|
|
|
|
# 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

# "Time: Mongolia has two time zones. Three westernmost provinces of

# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
|
|
# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus

|

# From Rives McDow (1999-12-13):
|
|
# Mongolia discontinued the use of daylight savings time in 1999; 1998
|
|
# being the last year it was implemented. The dates of implementation I am
|
|
# unsure of, but most probably it was similar to Russia, except for the time
|
|
# of implementation may have been different....
|
|
# Some maps in the past have indicated that there was an additional time

# zone in the eastern part of Mongolia, including the provinces of Dornod,

# Suhbaatar, and possibly Khentij.
|
|
|
|
# From Paul Eggert (1999-12-15):
|
|
# Naming and spelling is tricky in Mongolia.
|
|
# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
|
|
# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,

|
# and sometimes Jirgalanta (with variant spellings), but the name Hovd
|
|
# is good enough for our purposes.

# In addition to Mongolia starting daylight savings as reported earlier

# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),

# and ending at 00:01 local time October 6, 2002. This is what I was

|
# 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

# ISLAMABAD, March 6: Information and Media Development Minister Sheikh
|
|
# Rashid Ahmed on Thursday said the cabinet had reversed a previous
|
|
# decision to advance clocks by one hour in summer and put them back by
|
|
# one hour in winter with the aim of saving light hours and energy.
|
|
#
|
|
# The minister told a news conference that the experiment had rather
|
|
# shown 8 per cent higher consumption of electricity.

|
|
|
# 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:
|
|
#
|

|

# I guess more info may be available from the PA's web page (if/when they
|
|
# 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.

# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
|
|
# forwarded by Ephraim Silverberg:
|
|
#
|
|
# Despite the fact that Israel changed over to daylight savings time
|
|
# last week, the PLO Authority (PA) has decided not to turn its clocks
|
|
# one-hour forward at this time. As a sign of independence from Israeli rule,
|
|
# the PA has decided to implement DST in April.

|
# From Steffen Thorsen (2005-11-23):

# [The Tamil Tigers] never accepted the original 1996 time change and simply

|

# From Paul Eggert (2006-04-18):
|

# People who live in regions under Tamil control can use TZ='Asia/Calcutta',

# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
|
|
|
|
# From K Sethu (2006-04-25):
|
|
# 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):
