GMT+8

UTC+08:00 is an identifier for a time offset from UTC of +08:00.

With an estimated population of 1.708 billion living within the time zone, roughly 24% of the world population, it is the most populous time zone in the world, as well as a possible candidate for ASEAN Common Time.

This time zone is used in all predominantly Chinese-speaking regions, giving international Chinese websites and TV channels the same time.

In Indonesia, it is known as Central Indonesian Time ( id, Waktu Indonesia Tengah / WITA) while in Western Australia, it is known as Australian Western Standard Time.

Historical time offsets

The southern half of Vietnam (Republic of Vietnam) was formerly part of this time zone prior to the national reunification on 30 April 1975, making it one hour ahead of North Vietnam. After 1975, the whole country came under the North Vietnamese time zone, UTC+07:00.

According to Presidential Decree 41/1987, Indonesia's ex-province of Timor Timur used this time zone with neighboring East Nusa Tenggara and other provinces in Lesser Sunda Islands, parts of Kalimantan and Sulawesi until independence as East Timor, which the country changed to UTC+09:00 as official time zone.
