What's the timezone history of Ko Samui?
Ko Samui observes Indochina Time at UTC+7 alongside the rest of Thailand. The country adopted this single-zone offset in 1920, replacing locally varying solar time. Thailand has never operated daylight saving. The island's longitude around 100 degrees east places wall time roughly 20 minutes behind mean solar noon. Neighbouring countries Cambodia, Laos, and Vietnam share the same +7 offset. Western Indonesia's WIB zone matches, while Malaysia and Singapore observe +8, producing a one-hour step at the Thai-Malaysian land border.
