Frequently Asked Questions
What is the time difference between ICT and SAST?
During standard time, South African Standard Time is 5 hours behind Indochina Time.
Which countries use Indochina Time (ICT)?
Indochina Time is the official standard time for four Southeast Asian nations: Thailand, Vietnam, Cambodia, and Laos. All four countries observe a single, unified UTC+07:00 offset with no regional subdivisions.
Do Thailand and Vietnam observe Daylight Saving Time?
Neither Thailand nor Vietnam observes Daylight Saving Time, and neither do Cambodia or Laos. ICT remains fixed at UTC+07:00 throughout the entire year, with no seasonal clock changes.
Does South Africa observe Daylight Saving Time?
South Africa does not observe Daylight Saving Time and has not done so since 1944, remaining permanently fixed at UTC+2:00 every day of the year. This means that when European countries advance to CEST (UTC+2) each spring, SAST and Central European Summer Time reach an identical offset — a zero-difference alignment that makes South Africa one of Europe's most time-convenient offshore business partners during summer months.
Is SAST the same as European time?
SAST (UTC+2) matches Central European Summer Time (CEST, UTC+2) exactly during the European summer from late March to late October — meaning Johannesburg and Berlin, Paris, and Rome run on the same clock for roughly seven months of the year. During European winter, when the continent reverts to CET (UTC+1), SAST moves 1 hour ahead of Frankfurt and Paris, and 2 hours ahead of London (GMT, UTC+0).
