UTC8

UTC+08:00, or UTC+8, is a time offset that adds eight hours to Coordinated Universal Time (UTC). It is used as the standard time in parts of East Asia and Oceania and is sometimes referred to by regional names such as China Standard Time, Beijing Time, Hong Kong Time, Taiwan Standard Time, Singapore Time, Malaysia Time, Philippine Time, Brunei Time, and Western Australia Time.

Geographic distribution includes China, where the offset is used nationwide; Hong Kong, Macau, and Taiwan; Southeast Asian nations such as Singapore, Malaysia, the Philippines, and Brunei; and parts of Indonesia where Central Indonesia Time (WITA) is UTC+8. In Australia, Western Australia observes Australian Western Standard Time (AWST), which is UTC+8 year-round. Indonesia and Australia thus span UTC+8 in several areas, with other zones nearby at UTC+7 or UTC+9 in adjacent regions.

Daylight saving time is not observed in most UTC+8 regions, so the offset remains UTC+08:00 throughout the year. However, historical or temporary observances in some jurisdictions have varied in the past; current practice generally keeps UTC+8 year-round across the major areas that use this offset.

In computing, the offset is represented by multiple IANA time zone identifiers corresponding to the regions that observe it, such as Asia/Shanghai, Asia/Hong_Kong, Asia/Taipei, Asia/Singapore, Asia/Kuala_Lumpur, Asia/Manila, Asia/Macau, Asia/Brunei, Asia/Makassar, and Australia/Perth.
