It was never formally annexed to Egypt, 117943014Swollman# though. 118043014Swollman# 118143014Swollman# The rest of Palestine was under Jordanian rule at that time, formally 118243014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 118343014Swollman# the country's previous name of "the Hashemite Kingdom of the 118443014Swollman# Trans-Jordan"). So the rules for Jordan for that time apply. Major 118543014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 118643014Swollman# East Jerusalem. 118743014Swollman# 118843014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except 118943014Swollman# for East Jerusalem). They were on Israel time since then; there might 119043014Swollman# have been a Military Governor's order about time zones, but I'm not aware 119143014Swollman# of any (such orders may have been issued semi-annually whenever summer 119243014Swollman# time was in effect, but maybe the legal aspect of time was just neglected). 119343014Swollman# 119443014Swollman# The Palestinian Authority was established in 1993, and got hold of most 119543014Swollman# towns in the West Bank and Gaza by 1995.
