Timezones across South-East Asia
South-East Asia spans two main timezones: Indochina Time (ICT, UTC+7) covers Vietnam, Thailand, Cambodia, Laos; Singapore Time / Malaysia Time / Philippine Time / Hong Kong Time all sit at UTC+8. No country in the region observes DST, so offsets are fixed year-round. Singapore, KL and Manila together anchor the regional business day, with strong overlap into India (2.5-3 h ahead) and Australia (1-3 h behind).
