Therefore, Kazakhstan now has 976149514Swollman# two time zones, and difference between them is one hour. The zone 977149514Swollman# closer to UTC is the former Western zone (probably still called the 978149514Swollman# same), encompassing four provinces in the west: Aqtobe, Atyrau, 979149514Swollman# Mangghystau, and West Kazakhstan.

It was never formally annexed to Egypt, 134443014Swollman# though. 134543014Swollman# 134643014Swollman# The rest of Palestine was under Jordanian rule at that time, formally 134743014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 134843014Swollman# the country's previous name of "the Hashemite Kingdom of the 134943014Swollman# Trans-Jordan"). So the rules for Jordan for that time apply. Major 135043014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 135143014Swollman# East Jerusalem. 135243014Swollman# 135343014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except 135443014Swollman# for East Jerusalem). They were on Israel time since then; there might 135543014Swollman# have been a Military Governor's order about time zones, but I'm not aware 135643014Swollman# of any (such orders may have been issued semi-annually whenever summer 135743014Swollman# time was in effect, but maybe the legal aspect of time was just neglected). 135843014Swollman# 135943014Swollman# The Palestinian Authority was established in 1993, and got hold of most 136043014Swollman# towns in the West Bank and Gaza by 1995.
