513 514# According to the Office of the Secretary General of the Ministry of 515# Interior, there is NO set rule for Daylight-Savings/Standard time changes. 516# Each year they decide anew what havoc to wreak on the country. However, 517# there is a "supposed" set of rules which is subject to change depending 518# on the party the Minister of Interior, the size of the coalition 519# government, the phase of the moon and the direction of the wind. Hence, 520# changes may need to be made on a semi-annual basis. One thing is entrenched 521# in law, however: that there must be at least 150 days of daylight savings 522# time annually. Ever since 1993, the change to daylight savings time is 523# on a Thursday night from midnight IST to 1 a.m IDT. The change back to 524# standard time is on a Saturday night from midnight daylight savings time 525# to 11 p.m. standard time. 1996 is an exception to this rule where the 526# change back to standard time took place on Sunday night instead of Saturday 527# night to avoid conflicts with the Jewish New Year. 528 529# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 530Rule Zion 1989 only - Apr 30 0:00 1:00 D 531Rule Zion 1989 only - Sep 3 0:00 0 S 532Rule Zion 1990 only - Mar 25 0:00 1:00 D 533Rule Zion 1990 only - Aug 26 0:00 0 S 534Rule Zion 1991 only - Mar 24 0:00 1:00 D 535Rule Zion 1991 only - Sep 1 0:00 0 S 536Rule Zion 1992 only - Mar 29 0:00 1:00 D 537Rule Zion 1992 only - Sep 6 0:00 0 S 538Rule Zion 1993 only - Apr 2 0:00 1:00 D 539Rule Zion 1993 only - Sep 5 0:00 0 S 540 541# The dates for 1994-1995 were obtained from Office of the Spokeswoman for the 542# Ministry of Interior, Jerusalem, Israel.

839 840# From Amos Shapir <amos@nsof.co.il> (1998-02-15): 841# 842# From 1917 until 1948-05-15, all of Palestine, including the parts now 843# known as the Gaza Strip and the West Bank, was under British rule. 844# Therefore the rules given for Israel for that period, apply there too... 845# 846# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05 847# (except a short occupation by Israel from 1956-11 till 1957-03, but no 848# time zone was affected then). It was never formally annexed to Egypt, 849# though. 850# 851# The rest of Palestine was under Jordanian rule at that time, formally 852# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 853# the country's previous name of "the Hashemite Kingdom of the 854# Trans-Jordan"). So the rules for Jordan for that time apply. Major 855# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 856# East Jerusalem. 857# 858# Both areas were occupied by Israel in June 1967, but not annexed (except 859# for East Jerusalem). They were on Israel time since then; there might 860# have been a Military Governor's order about time zones, but I'm not aware 861# of any (such orders may have been issued semi-annually whenever summer 862# time was in effect, but maybe the legal aspect of time was just neglected). 863# 864# The Palestinian Authority was established in 1993, and got hold of most 865# towns in the West Bank and Gaza by 1995. I know that in order to 866# demonstrate...independence, they have been switching to 867# summer time and back on a different schedule than Israel's, but I don't 868# know when this was started, or what algorithm is used (most likely the 869# Jordanian one). 870# 871# To summarize, the table should probably look something like that: 872# 873# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- 874# ------------+-----------+-----------+-----------+----------- 875# Israel | Zion | Zion | Zion | Zion 876# West bank | Zion | Jordan | Zion | Jordan 877# Gaza | Zion | Egypt | Zion | Jordan 878# 879# I guess more info may be available from the PA's web page (if/when they 880# have one). 881 882# From Paul Eggert (1998-02-25): 883# Shanks writes that Gaza did not observe DST until 1957, but we'll go 884# with Shapir and assume that it observed DST from 1940 through 1947, 885# and that it used Jordanian rules starting in 1996. 886# We don't yet need a separate entry for the West Bank, since 887# the only differences between it and Gaza that we know about 888# occurred before our cutoff date of 1970. 889# However, as we get more information, we may need to add entries 890# for parts of the West Bank as they transitioned from Israel's rules 891# to Palestine's rules. If you have more info about this, please 892# send it to tz@elsie.nci.nih.gov for incorporation into future editions. 893 894# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time, 895# forwarded by Ephraim Silverberg: 896# 897# Despite the fact that Israel changed over to daylight savings time 898# last week, the PLO Authority (PA) has decided not to turn its clocks 899# one-hour forward at this time. As a sign of independence from Israeli rule, 900# the PA has decided to implement DST in April. 901 |
