It was never formally annexed to Egypt, 136743014Swollman# though. 136843014Swollman# 136943014Swollman# The rest of Palestine was under Jordanian rule at that time, formally 137043014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 137143014Swollman# the country's previous name of "the Hashemite Kingdom of the 137243014Swollman# Trans-Jordan"). So the rules for Jordan for that time apply. Major 137343014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 137443014Swollman# East Jerusalem. 137543014Swollman# 137643014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except 137743014Swollman# for East Jerusalem). They were on Israel time since then; there might 137843014Swollman# have been a Military Governor's order about time zones, but I'm not aware 137943014Swollman# of any (such orders may have been issued semi-annually whenever summer 138043014Swollman# time was in effect, but maybe the legal aspect of time was just neglected). 138143014Swollman# 138243014Swollman# The Palestinian Authority was established in 1993, and got hold of most 138343014Swollman# towns in the West Bank and Gaza by 1995.
