It was never formally annexed to Egypt, 1546# though. 1547# 1548# The rest of Palestine was under Jordanian rule at that time, formally 1549# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1550# the country's previous name of "the Hashemite Kingdom of the 1551# Trans-Jordan"). So the rules for Jordan for that time apply. Major 1552# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 1553# East Jerusalem. 1554# 1555# Both areas were occupied by Israel in June 1967, but not annexed (except 1556# for East Jerusalem).

It was never formally annexed to Egypt, 1568# though. 1569# 1570# The rest of Palestine was under Jordanian rule at that time, formally 1571# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 1572# the country's previous name of "the Hashemite Kingdom of the 1573# Trans-Jordan"). So the rules for Jordan for that time apply. Major 1574# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 1575# East Jerusalem. 1576# 1577# Both areas were occupied by Israel in June 1967, but not annexed (except 1578# for East Jerusalem). They were on Israel time since then; there might 1579# have been a Military Governor's order about time zones, but I'm not aware 1580# of any (such orders may have been issued semi-annually whenever summer 1581# time was in effect, but maybe the legal aspect of time was just neglected). 1582# 1583# The Palestinian Authority was established in 1993, and got hold of most 1584# towns in the West Bank and Gaza by 1995.
