Time in Thailand
Thailand uses the UTC+7 time zone, with no observation of daylight saving time. The abbreviation for Thailand Standard Time is "THA".
In 2001,[1] then-Prime Minister Thaksin Shinawatra announced intentions to change the country's time zone to UTC+8 to be in line with Singapore, Malaysia, China, Hong Kong. This was met with much criticism and resistance, and the plan was withdrawn.

Date notation

Time notation
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.
