*unless I've missed something in this long thread, there has been (to my
knowledge) no mention made of Taiwan and cities thereof. Although it lies
in the time zone commonly known as CST (China Standard Time) Taiwan, for
all practical purposes, is distinct from other entities in the same time
zone, viz. Australia (Perth), China 中国, Malaysia, Philippines, Singapore.
Without revisiting the respective positions of Beijing and Taipei regarding
what China calls its "one China policy" under which Taiwan is its 23rd
province, the practical realities of Taiwan, as well as its political,
monetary and other features, make it separate from China. And if the
demographic criterion determines the inclusion of a country and/or city in
the time zone list, Taiwan is the sixteenth most densely populated country
on earth, and Taipei's population registers above 2.6 million (2006 census).
*In light of the above, and simply as someone who often has to take
different time zones into account, I suggest that, for practical reasons,
Taiwan 臺灣  (or 台湾 <http://fr.wiktionary.org/wiki/%E5%8F%B0%E6%B9%BE> in
simplified orthography) and at least the city of Taipei 臺北 (台北) be given
the same treatment as, say, Beijing 北京, Kuala Lumpur, Manila, Perth, or
