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: # # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- # ------------+-----------+-----------+-----------+----------- # Israel | Zion | Zion | Zion | Zion # West bank | Zion | Jordan | Zion | Jordan # Gaza | Zion | Egypt | Zion | Jordan # # I guess more info may be available from the PA's web page (if/when they # have one). # From Paul Eggert (1998-02-25): # Shanks writes that Gaza did not observe DST until 1957, but we'll 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.
