Thailand Standard Time

 

Thailand Standard Time

Thailand follows UTC+7, which is 7 hours ahead of Greenwich Mean Time and Coordinated Universal Time. The local mean time in Bangkok was originally GMT+06:42:04.[1] Thailand used this local mean time until 1920, when they changed to Indochina Time GMT+07:00.

History

Standardisation of time in Thailand

Thailand declared that people would move their clocks ahead by 17-minutes 56-seconds to match the time in use in Southeast Asia (UTC+06:42:04 hrs an UTC+07:00:00 ahead of Greenwich Mean Time) in 31 March 1920. The time was switched on 1 April 1920 at 06:00 (old time) to 06:17:56 (new time).

Timekeeper

On 1 January 1990, the Thai Cabinet appointed the Royal Thai Navy as the official timekeeper of Thailand. The Thai Standard Time is derived from 5-atomic clocks maintained by Royal Thai Navy.
