I appeal to those readers of the mailing list capable of reading Chinese / mandarin to look for sources which could - document that multiple timezones where indeed maintained before May 1980 (e.g. railway or airline time tables of that period), - document the transition to a unified zone in May 1980 (legal text, newspaper articles mentioning the time change) - document the government decision for a unified timezone in 1949
My gut feeling is that the unified timezone was introduced in 1949, and that Shanks got it wrong. We need documents to establish that.
I refer to: http://www.timetableimages.com/ttimages/complete/caac56/<http://bit.ly/1nMKS46>, which has clean scans of the Civil Aviation Administration of China's 1956 timetable. As far as I can make out from calculating flight times, all places in China that CAAC flew to had the same timezone. -- Sanjeev Gupta +65 98551208 http://www.linkedin.com/in/ghane
