About IST and ICT
IST (India Standard Time) covers India and is anchored to the IANA zone Asia/Kolkata. It does not observe daylight saving time — the offset stays fixed all year.
ICT (Indochina Time) covers Thailand, Vietnam, Cambodia, and Laos via Asia/Bangkok. It does not observe daylight saving time.
Neither IST nor ICT observes DST, so the offset between them is constant year-round at 1h 30m.
