- Australia (AWST — Australian Western Standard Time)
Western Australia began a three-year trial of summer (daylight saving) time on December 3, 2006. Daylight saving time was used from October through March, with the late start in 2006 due to late passage of the relevant legislation. A referendum held on May 19, 2009 resulted in a majority vote against daylight saving, which is therefore not currently used in WA.
The whole of the People's Republic of China has the same time, which makes this time zone exceptionally wide. In the extreme west of China the sun is at its highest at 15:00, in the extreme east at 11:00. It also means that on the short (76 km) frontier with Afghanistan, the official time change is 3 hours and 30 minutes. The two western autonomous regions of China, Xinjiang and Tibet, were in UTC+6 during the Republic era (1912–1949), but were moved to UTC+8 after the founding of the People's Republic of China in 1949. Today, residents of the two autonomous regions do everything 2 hours late. For example, lunch is at 14:00 and business hours end around 19:00.[masapul a dakamaten]
In 1904, Royal Observatory Hong Kong began to adopt Greenwich Mean Time as the basis for Hong Kong Time (8 hours in advance of Greenwich Mean Time). The practice pre-dates the establishment of Republic of China (1911) and People's Republic of China (1949). Prior World War II, the Hong Kong Time was determined by astronomical observations at the Observatory using a 6-inch Lee Equatorial and a 3-inch Transit Circle. Now, the current time can be obtained from the Observatory's Network Time Server.
The more populous Peninsular Malaysia is geographically in UTC+7, but changed to UTC+8 in 1982 to follow that of Malaysian Borneo (which makes up only 20% of total population), so that the whole country lies in the same time zone.
In 1895, when Japan took over the island of Taiwan (including the Pescadores), Taiwan was placed within Japan's Western Standard Time (UTC+8) along with the Yaeyama Islands and Miyako Island (now the southwestern part of Okinawa Prefecture, Japan). However, in 1937, Japan abolished its Western Standard Time so Taiwan then observed Japan Standard Time (UTC+09:00). Taiwan reverted back to UTC+08 after World War II with intermittent usage of daylight saving time until 1979.
