Time in Thailand
In 2001, then-Prime Minister Thaksin Shinawatra announced intentions to change the country's UTC offset to UTC+08:00 to be in line with Singapore, Malaysia, China, Hong Kong & The Philippines. This was met with much criticism and resistance. The plan was later withdrawn.
Thailand mainly uses the Buddhist Era which is 543 years ahead of the Gregorian year. The year AD 2013 is indicated as 2556 BE in Thailand.
Next to the 12-hour and 24-hour clock system, a 6-hour clock system is also used, especially in spoken language. It counts 4 times from 1 to 6, with different additional words to make the distinction for night, morning, afternoon, and evening.
Thailand also adopted ISO 8601 under national standard: TIS 1111:2535 in 1992.
