486# Go with Shanks before September 1991, and with Pournader thereafter.
478# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates.
479# The Persian calendar is based on the sun, and dates after around 2050
480# are approximate; stop after 2037 when 32-bit time_t's overflow.
487# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
488# stopping after 2037 when 32-bit time_t's overflow.
489# That cal-persia used Birashk's approximation, which disagrees with the solar
490# calendar predictions for the year 2025, so I corrected those dates by hand.
481#
491#
492# From Oscar van Vlijmen (2005-03-30), writing about future
493# discrepancies between cal-persia and the Iranian calendar:
494# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
495# the vernal equinox and that gets so close to 12:00 some local
496# Iranian time that the definition of the correct location needs to be
497# known exactly, amongst other factors. 2157 is even closer:
498# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
499# no interpretation problem whatsoever. By the way, another instant
500# in the near future where there will be a discrepancy between
501# arithmetical and astronomical Iranian calendars will be in 2058:
502# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
503# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
504# 2058-03-21 for 1 Farvardin 1437 (astronomical).

543# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
544# the U.S. edition) on the Iraqi Kurds contains a paragraph:
545# "The three northern provinces ... switched their clocks this spring and
546# are an hour ahead of Baghdad."
547#
548# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
549# In the past, some Kurdish nationalists, as a protest to the Iraqi
550# Government, did not adhere to daylight saving time. They referred
551# to daylight saving as Saddam time. But, as of today, the time zone
552# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
553#
554# So we'll ignore the Economist's claim.

578# From Ephraim Silverberg (2001-01-11):
579#
580# I coined "IST/IDT" circa 1988. Until then there were three
581# different abbreviations in use:
582#
583# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
584# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
585# EEST Eastern Europe Standard Time [used by almost everyone else]
586#
587# Since timezones should be called by country and not capital cities,
588# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
589# EEST was equally unacceptable. Since "zonal" was not compatible with
590# any other timezone abbreviation, I felt that 'IST' was the way to go
591# and, indeed, it has received almost universal acceptance in timezone
592# settings in Israeli computers.
593#
594# In any case, I am happy to share timezone abbreviations with India,
595# high on my favorite-country list (and not only because my wife's
596# family is from India).

567# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
568# the U.S. edition) on the Iraqi Kurds contains a paragraph:
569# "The three northern provinces ... switched their clocks this spring and
570# are an hour ahead of Baghdad."
571#
572# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
573# In the past, some Kurdish nationalists, as a protest to the Iraqi
574# Government, did not adhere to daylight saving time. They referred
575# to daylight saving as Saddam time. But, as of today, the time zone
576# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
577#
578# So we'll ignore the Economist's claim.

666# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,

643
644# According to the Office of the Secretary General of the Ministry of
645# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
646# One thing is entrenched in law, however: that there must be at least 150
647# days of daylight savings time annually. From 1993-1998, the change to
648# daylight savings time was on a Friday morning from midnight IST to
649# 1 a.m IDT; up until 1998, the change back to standard time was on a
650# Saturday night from midnight daylight savings time to 11 p.m. standard
651# time. 1996 is an exception to this rule where the change back to standard
652# time took place on Sunday night instead of Saturday night to avoid
653# conflicts with the Jewish New Year. In 1999, the change to
654# daylight savings time was still on a Friday morning but from
655# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
656# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
657# 1999 only. In the year 2000, the change to daylight savings time was
658# similar to 1999, but although the change back will be on a Friday, it
659# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
660# changes to/from will take place at 1 a.m. old time, but now there is no
661# rule as to what day of the week it will take place in as the start date
662# (except in 2003) is the night after the Passover Seder (i.e. the eve
663# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
664# (except in 2002) is three nights before Yom Kippur [Day of Atonement]

739# Here are guesses for rules after 2004.
740# They are probably wrong, but they are more likely than no DST at all.

763# The proposed law agreed upon by the Knesset Interior Committee on
764# 2005-02-14 is that, for 2005 and beyond, DST starts at 02:00 the
765# last Friday before April 2nd (i.e. the last Friday in March or April
766# 1st itself if it falls on a Friday) and ends at 02:00 on the Saturday

776# along with Ed Reingold's cal-hebrew in GNU Emacs 21.4,
777# to generate the transitions in this list.
778# (I replaced "lastFri" with "Fri>=26" by hand.)
779# The spring transitions below all correspond to the following Rule:
780#
781# Rule Zion 2005 max - Mar Fri>=26 2:00 1:00 D
782#
783# but older zic implementations (e.g., Solaris 8) do not support
784# "Fri>=26" to mean April 1 in years like 2005, so for now we list the

750# From Ephraim Silverberg (2003-03-23):
751#
752# Minister of Interior Poraz has announced that he will respect the law
753# passed in July 2000 (proposed at the time jointly by himself and
754# then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence,
755# the dates for 2003 and 2004 remain unchanged....
756#
757# As far as 2005 and beyond, no dates have been set. However, the
758# minister has mentioned that he wishes to propose to move Israel's
759# timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during
760# the summer months (i.e. GMT+4). However, no legislation in this
761# direction is expected until the latter part of 2004 which is a long
762# time off in terms of Israeli politics.
763
837
764# (2004-09-20):
765# The latest rumour, however, is that in 2005, when the clock changes to
766# Daylight Saving Time (date as yet unknown), the move will be a two-hour leap
767# forward (from UTC+0200 to UTC+0400) and then, in the fall, the clock will
768# move back only an hour to UTC+0300 thus effectively moving Israel's timezone
769# from UTC+0200 to UTC+0300. However, no actual draft has been put before the
770# Knesset (Israel's Parliament) though the intention is to do so this
771# month [2004-09].
772
838
773# (2004-09-26):
774# Even though the draft law for the above did pass the Ministerial Committee
775# for Legislative Matters three months ago, it was voted down in today's
776# Cabinet meeting. The current suggestion is to keep the current timezone at
777# UTC+0200 but have an extended period of Daylight Saving Time (UTC+0300) from
778# the beginning of Passover holiday in the spring to after the Tabernacle
779# holiday in the fall (i.e. the dates of which are governed by the Hebrew
780# calendar but this means at least 184 days of DST). However, this is only a
781# suggestion that was raised in today's cabinet meeting and has not yet been
782# drafted.

953# From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
954# </a>
955# The Government of Kazakhstan passed a resolution March 15 abolishing
956# daylight saving time citing lack of economic benefits and health
957# complications coupled with a decrease in productivity.
896#
958#
959# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
960# ... what happened was that the former Kazakhstan Eastern time zone
961# was "blended" with the Central zone. Therefore, Kazakhstan now has
962# two time zones, and difference between them is one hour. The zone
963# closer to UTC is the former Western zone (probably still called the
964# same), encompassing four provinces in the west: Aqtobe, Atyrau,
965# Mangghystau, and West Kazakhstan. The other zone encompasses
966# everything else.... I guess that would make Kazakhstan time zones
967# de jure UTC+5 and UTC+6 respectively.

1170# "Time: Mongolia has two time zones. Three westernmost provinces of

1176# Mongolia discontinued the use of daylight savings time in 1999; 1998

1180# Some maps in the past have indicated that there was an additional time

1185# Naming and spelling is tricky in Mongolia.

1219# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1321# From Amos Shapir (1998-02-15):
1220#
1221# From 1917 until 1948-05-15, all of Palestine, including the parts now
1222# known as the Gaza Strip and the West Bank, was under British rule.
1223# Therefore the rules given for Israel for that period, apply there too...
1224#
1225# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1226# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1227# time zone was affected then). It was never formally annexed to Egypt,
1228# though.
1229#
1230# The rest of Palestine was under Jordanian rule at that time, formally
1231# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1232# the country's previous name of "the Hashemite Kingdom of the
1233# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1234# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1235# East Jerusalem.
1236#
1237# Both areas were occupied by Israel in June 1967, but not annexed (except
1238# for East Jerusalem). They were on Israel time since then; there might
1239# have been a Military Governor's order about time zones, but I'm not aware
1240# of any (such orders may have been issued semi-annually whenever summer
1241# time was in effect, but maybe the legal aspect of time was just neglected).
1242#
1243# The Palestinian Authority was established in 1993, and got hold of most
1244# towns in the West Bank and Gaza by 1995. I know that in order to
1245# demonstrate...independence, they have been switching to
1246# summer time and back on a different schedule than Israel's, but I don't
1247# know when this was started, or what algorithm is used (most likely the
1248# Jordanian one).
1249#
1250# To summarize, the table should probably look something like that:
1251#
1252# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1253# ------------+-----------+-----------+-----------+-----------
1254# Israel | Zion | Zion | Zion | Zion
1255# West bank | Zion | Jordan | Zion | Jordan
1256# Gaza | Zion | Egypt | Zion | Jordan
1257#

1323# From 1917 until 1948-05-15, all of Palestine, including the parts now
1324# known as the Gaza Strip and the West Bank, was under British rule.
1325# Therefore the rules given for Israel for that period, apply there too...
1326#
1327# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1328# (except a short occupation by Israel from 1956-11 till 1957-03, but no
1329# time zone was affected then). It was never formally annexed to Egypt,
1330# though.
1331#
1332# The rest of Palestine was under Jordanian rule at that time, formally
1333# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1334# the country's previous name of "the Hashemite Kingdom of the
1335# Trans-Jordan"). So the rules for Jordan for that time apply. Major
1336# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1337# East Jerusalem.
1338#
1339# Both areas were occupied by Israel in June 1967, but not annexed (except
1340# for East Jerusalem). They were on Israel time since then; there might
1341# have been a Military Governor's order about time zones, but I'm not aware
1342# of any (such orders may have been issued semi-annually whenever summer
1343# time was in effect, but maybe the legal aspect of time was just neglected).
1344#
1345# The Palestinian Authority was established in 1993, and got hold of most
1346# towns in the West Bank and Gaza by 1995. I know that in order to
1347# demonstrate...independence, they have been switching to
1348# summer time and back on a different schedule than Israel's, but I don't
1349# know when this was started, or what algorithm is used (most likely the
1350# Jordanian one).
1351#
1352# To summarize, the table should probably look something like that:
1353#
1354# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1355# ------------+-----------+-----------+-----------+-----------
1356# Israel | Zion | Zion | Zion | Zion
1357# West bank | Zion | Jordan | Zion | Jordan
1358# Gaza | Zion | Egypt | Zion | Jordan
