The government of the Xinjiang 426200835Sedwin# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 427200835Sedwin# local governments such as the Urumqi city government use both times in 428200835Sedwin# publications, referring to what is popularly called Xinjiang time as 429200835Sedwin# "Urumqi time."

It was never formally annexed to Egypt, 201343014Swollman# though. 201443014Swollman# 201543014Swollman# The rest of Palestine was under Jordanian rule at that time, formally 201643014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 201743014Swollman# the country's previous name of "the Hashemite Kingdom of the 201843014Swollman# Trans-Jordan"). So the rules for Jordan for that time apply. Major 201943014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 202043014Swollman# East Jerusalem. 202143014Swollman# 202243014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except 202343014Swollman# for East Jerusalem).
