14# Gwillim Law writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually. Law sent in several helpful summaries
18# of the IATA's data after 1990.

92# in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
93# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

182# No they don't. See TIME mag, 1986-02-17 p.52. Even though
183# China is across 4 physical time zones, before Feb 1, 1986 only the
184# Peking (Bejing) time zone was recognized. Since that date, China
185# has two of 'em -- Peking's and Urumqi (named after the capital of

557# From Oscar van Vlijmen (2005-03-30), writing about future

559# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
560# the vernal equinox and that gets so close to 12:00 some local
561# Iranian time that the definition of the correct location needs to be
562# known exactly, amongst other factors. 2157 is even closer:
563# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
564# no interpretation problem whatsoever. By the way, another instant
565# in the near future where there will be a discrepancy between
566# arithmetical and astronomical Iranian calendars will be in 2058:
567# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of

701# From Ephraim Silverberg (2001-01-11):
702#
703# I coined "IST/IDT" circa 1988. Until then there were three
704# different abbreviations in use:
705#
706# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
707# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
708# EEST Eastern Europe Standard Time [used by almost everyone else]
709#
710# Since timezones should be called by country and not capital cities,
711# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
712# EEST was equally unacceptable. Since "zonal" was not compatible with
713# any other timezone abbreviation, I felt that 'IST' was the way to go
714# and, indeed, it has received almost universal acceptance in timezone
715# settings in Israeli computers.
716#
717# In any case, I am happy to share timezone abbreviations with India,
718# high on my favorite-country list (and not only because my wife's
719# family is from India).

768# According to the Office of the Secretary General of the Ministry of
769# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
770# One thing is entrenched in law, however: that there must be at least 150
771# days of daylight savings time annually. From 1993-1998, the change to
772# daylight savings time was on a Friday morning from midnight IST to
773# 1 a.m IDT; up until 1998, the change back to standard time was on a
774# Saturday night from midnight daylight savings time to 11 p.m. standard
775# time. 1996 is an exception to this rule where the change back to standard
776# time took place on Sunday night instead of Saturday night to avoid
777# conflicts with the Jewish New Year. In 1999, the change to
778# daylight savings time was still on a Friday morning but from
779# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
780# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
781# 1999 only. In the year 2000, the change to daylight savings time was
782# similar to 1999, but although the change back will be on a Friday, it
783# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
784# changes to/from will take place at 1 a.m. old time, but now there is no
785# rule as to what day of the week it will take place in as the start date
786# (except in 2003) is the night after the Passover Seder (i.e. the eve
787# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
788# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
789# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

951# Occupation authorities imposed daylight-saving time on Japan on

953# daylight-saving time just three days after the bill was passed generated
954# deep hatred of the concept.... The Diet unceremoniously passed a bill to
955# dump the unpopular system in October 1951, less than a month after the San

1092# two time zones, and difference between them is one hour. The zone
1093# closer to UTC is the former Western zone (probably still called the

984263bc
MD
1479#
1480# From 1917 until 1948-05-15, all of Palestine, including the parts now
1481# known as the Gaza Strip and the West Bank, was under British rule.
1482# Therefore the rules given for Israel for that period, apply there too...
1483#
1484# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1485# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1486# time zone was affected then). It was never formally annexed to Egypt,
1487# though.
1488#
1489# The rest of Palestine was under Jordanian rule at that time, formally
1490# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1491# the country's previous name of "the Hashemite Kingdom of the
1492# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1493# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1494# East Jerusalem.
1495#
1496# Both areas were occupied by Israel in June 1967, but not annexed (except
1497# for East Jerusalem). They were on Israel time since then; there might
1498# have been a Military Governor's order about time zones, but I'm not aware
1499# of any (such orders may have been issued semi-annually whenever summer
1500# time was in effect, but maybe the legal aspect of time was just neglected).
1501#
1502# The Palestinian Authority was established in 1993, and got hold of most
1503# towns in the West Bank and Gaza by 1995. I know that in order to
1504# demonstrate...independence, they have been switching to
1505# summer time and back on a different schedule than Israel's, but I don't
1506# know when this was started, or what algorithm is used (most likely the
1507# Jordanian one).
1508#
1509# To summarize, the table should probably look something like that:
1510#
1511# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1512# ------------+-----------+-----------+-----------+-----------
1513# Israel | Zion | Zion | Zion | Zion
1514# West bank | Zion | Jordan | Zion | Jordan
1515# Gaza | Zion | Egypt | Zion | Jordan

1518# have one).

1523# and that it used Jordanian rules starting in 1996.
1524# We don't yet need a separate entry for the West Bank, since
1525# the only differences between it and Gaza that we know about
1526# occurred before our cutoff date of 1970.
1527# However, as we get more information, we may need to add entries

1706# as that zone has agreed with the Tamil areas since our cutoff date of 1970.
1707
1708# From K Sethu (2006-04-25):
1709# I think the abbreviation LKT originated from the world of computers at
1710# the time of or subsequent to the time zone changes by SL Government
1711# twice in 1996 and probably SL Government or its standardization
1712# agencies never declared an abbreviation as a national standard.
1713#
1714# I recollect before the recent change the government annoucemments
1715# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1716# Time and no mention was made about the abbreviation.
1717#
1718# If we look at Sri Lanka Department of Government's "Official News
1719# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1720# use SLT as abbreviation in time stamp at the beginning of each news
1721# item....
1722#
1723# Within Sri Lanka I think LKT is well known among computer users and
1724# adminsitrators. In my opinion SLT may not be a good choice because the
1725# nation's largest telcom / internet operator Sri Lanka Telcom is well
1726# known by that abbreviation - simply as SLT (there IP domains are
1727# slt.lk and sltnet.lk).
1728#
1729# But if indeed our government has adopted SLT as standard abbreviation
1730# (that we have not known so far) then it is better that it be used for
1731# all computers.
1732
1733# From Paul Eggert (2006-04-25):
1734# One possibility is that we wait for a bit for the dust to settle down
1735# and then see what people actually say in practice.
