About IST and GST
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.
GST (Gulf Standard Time) covers UAE and Oman via Asia/Dubai. It does not observe daylight saving time.
Neither IST nor GST observes DST, so the offset between them is constant year-round at 1h 30m.
