Frequently Asked Questions
What is the time difference between ICT and BRT?
During standard time, Brasília Time is 10 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 Brazil observe Daylight Saving Time?
Brazil officially abolished Daylight Saving Time by presidential decree in April 2019, ending a practice that had been observed in the country's southeastern states since 1985. BRT has remained fixed at UTC-3:00 every day of the year since then, meaning the B3 stock exchange, federal government, and all Brazilian commercial operations run on a permanent, unchanging offset.
Is BRT the same as Argentina Time (ART)?
BRT (Brasília Time) and ART (Argentina Time) share the identical UTC-3:00 offset and neither country observes Daylight Saving Time, making São Paulo and Buenos Aires permanently synchronized on the same clock. Despite the different official designations, a meeting set for 10:00 BRT in São Paulo falls at exactly 10:00 ART in Buenos Aires — a fixed relationship that never shifts seasonally.
