A 1966 legislative error legally placed southern Idaho in the North American Central Time Zone. The 1966 Uniform Time Act added Atlantic standard time as the first zone, renumbering mountain standard time from the third zone to the fourth zone,[2] but the portion of the original 1918 Standard Time Act which placed southern Idaho in the "third zone"[3] was not changed in 1966. Nevertheless, southern Idaho is now officially in the Mountain Time Zone according to the Code of Federal Regulations.[4]

o Western Australia (most of state)**

Western Australia began a three-year experiment with usage of summer (daylight saving) time on 3 December 2006. Daylight saving time will be used from October through March, with the late start in 2006 due to late passage of the relevant legislation. A referendum will be held in the autumn or winter of 2009 to determine whether daylight saving time usage will be permanent.

* Brunei
* People's Republic of China

Note that 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 hour ends around 19:00.[citation needed]

* Hong Kong and Macau SAR
* Republic of China (Taiwan)

In 1895, when Japan took over Taiwan Island, 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+9). Taiwan reverted back to UTC+8 after World War II with intermittent usage of daylight saving time until 1979.
