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),

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

384# is now just four hours ahead of Greenwich Mean Time, rather than five hours

559# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for

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

646# From Ephraim Silverberg (2001-01-11):
647#
648# I coined "IST/IDT" circa 1988. Until then there were three
649# different abbreviations in use:
650#
651# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
652# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
653# EEST Eastern Europe Standard Time [used by almost everyone else]
654#
655# Since timezones should be called by country and not capital cities,
656# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
657# EEST was equally unacceptable. Since "zonal" was not compatible with
658# any other timezone abbreviation, I felt that 'IST' was the way to go
659# and, indeed, it has received almost universal acceptance in timezone
660# settings in Israeli computers.
661#
662# In any case, I am happy to share timezone abbreviations with India,
663# high on my favorite-country list (and not only because my wife's
664# family is from India).

713# According to the Office of the Secretary General of the Ministry of
714# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
715# One thing is entrenched in law, however: that there must be at least 150
716# days of daylight savings time annually. From 1993-1998, the change to
717# daylight savings time was on a Friday morning from midnight IST to
718# 1 a.m IDT; up until 1998, the change back to standard time was on a
719# Saturday night from midnight daylight savings time to 11 p.m. standard
720# time. 1996 is an exception to this rule where the change back to standard
721# time took place on Sunday night instead of Saturday night to avoid
722# conflicts with the Jewish New Year. In 1999, the change to
723# daylight savings time was still on a Friday morning but from
724# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
725# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
726# 1999 only. In the year 2000, the change to daylight savings time was
727# similar to 1999, but although the change back will be on a Friday, it
728# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
729# changes to/from will take place at 1 a.m. old time, but now there is no
730# rule as to what day of the week it will take place in as the start date
731# (except in 2003) is the night after the Passover Seder (i.e. the eve
732# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
733# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
734# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

896# Occupation authorities imposed daylight-saving time on Japan on
897# [1948-05-01].... But lack of prior debate and the execution of
898# daylight-saving time just three days after the bill was passed generated
899# deep hatred of the concept.... The Diet unceremoniously passed a bill to
900# dump the unpopular system in October 1951, less than a month after the San
901# Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%

1374# From Rives McDow (2002-03-13):
1375# I have been advised that Pakistan has decided to adopt dst on a
1376# TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1377# and ending at 00:01 local time October 6, 2002. This is what I was
1378# told, but I believe that the actual time of change may be 00:00; the
1379# 00:01 was to make it clear which day it was on.

1383# http://www.pak.gov.pk/public/news/app/app06_dec.htm
1384# (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1385# advance the clocks by one hour on the night between the first
1386# Saturday and Sunday of April and revert to the original position on
1387# 15th October each year". This agrees with McDow's 04-07 at 00:00,
1388# but disagrees about the October transition, and makes it sound like
1389# it's not on a trial basis. Also, the "between the first Saturday

1424#
1425# From 1917 until 1948-05-15, all of Palestine, including the parts now
1426# known as the Gaza Strip and the West Bank, was under British rule.
1427# Therefore the rules given for Israel for that period, apply there too...
1428#
1429# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1430# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1431# time zone was affected then). It was never formally annexed to Egypt,
1432# though.
1433#
1434# The rest of Palestine was under Jordanian rule at that time, formally
1435# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1436# the country's previous name of "the Hashemite Kingdom of the
1437# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1438# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1439# East Jerusalem.
1440#
1441# Both areas were occupied by Israel in June 1967, but not annexed (except
1442# for East Jerusalem). They were on Israel time since then; there might
1443# have been a Military Governor's order about time zones, but I'm not aware
1444# of any (such orders may have been issued semi-annually whenever summer
1445# time was in effect, but maybe the legal aspect of time was just neglected).
1446#
1447# The Palestinian Authority was established in 1993, and got hold of most
1448# towns in the West Bank and Gaza by 1995. I know that in order to
1449# demonstrate...independence, they have been switching to
1450# summer time and back on a different schedule than Israel's, but I don't
1451# know when this was started, or what algorithm is used (most likely the
1452# Jordanian one).
1453#
1454# To summarize, the table should probably look something like that:
1455#
1456# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1457# ------------+-----------+-----------+-----------+-----------
1458# Israel | Zion | Zion | Zion | Zion
1459# West bank | Zion | Jordan | Zion | Jordan
1460# Gaza | Zion | Egypt | Zion | Jordan
1461#
1462# I guess more info may be available from the PA's web page (if/when they
1463# have one).

1467# with Shapir and assume that it observed DST from 1940 through 1947,
1468# and that it used Jordanian rules starting in 1996.
1469# We don't yet need a separate entry for the West Bank, since
1470# the only differences between it and Gaza that we know about
1471# occurred before our cutoff date of 1970.
1472# However, as we get more information, we may need to add entries
1473# for parts of the West Bank as they transitioned from Israel's rules
1474# to Palestine's rules. If you have more info about this, please

1480# Despite the fact that Israel changed over to daylight savings time
1481# last week, the PLO Authority (PA) has decided not to turn its clocks

1642# From K Sethu (2006-04-25):
1643# I think the abbreviation LKT originated from the world of computers at
1644# the time of or subsequent to the time zone changes by SL Government
1645# twice in 1996 and probably SL Government or its standardization
1646# agencies never declared an abbreviation as a national standard.
1647#
1648# I recollect before the recent change the government annoucemments
1649# mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1650# Time and no mention was made about the abbreviation.
1651#
1652# If we look at Sri Lanka Department of Government's "Official News
1653# Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1654# use SLT as abbreviation in time stamp at the beginning of each news
1655# item....
1656#
1657# Within Sri Lanka I think LKT is well known among computer users and
1658# adminsitrators. In my opinion SLT may not be a good choice because the
1659# nation's largest telcom / internet operator Sri Lanka Telcom is well
1660# known by that abbreviation - simply as SLT (there IP domains are
1661# slt.lk and sltnet.lk).
1662#
1663# But if indeed our government has adopted SLT as standard abbreviation
1664# (that we have not known so far) then it is better that it be used for
1665# all computers.
