Time zone history and practice
China spans about five geographic time zones but uses one official time, China Standard Time (UTC plus 8), also called Beijing Time. The unified time was adopted in 1949. As a result, in far western Xinjiang the sun can rise at around 10 a.m. clock time, and some residents informally use Xinjiang Time (UTC plus 6) in daily life. China has no daylight saving time since 1991.
Conversions
When it is 9 a.m. in Beijing it is 8 p.m. the previous day in New York in winter (13 hours behind), 6 p.m. the previous day in Los Angeles (16 hours behind) and 1 a.m. in London in winter (8 hours behind). Singapore, Perth, Taipei, Manila and Hong Kong share the same UTC plus 8 offset. Chinese official working hours are typically 9 a.m. to 5 or 6 p.m., with a lunch break often extending to 1 or 2 hours.
