About WAT and IST
WAT (West Africa Time) covers Nigeria, Cameroon, and Angola and is anchored to the IANA zone Africa/Lagos. It does not observe daylight saving time — the offset stays fixed all year.
IST (India Standard Time) covers India via Asia/Kolkata. It does not observe daylight saving time.
Neither WAT nor IST observes DST, so the offset between them is constant year-round at 4h 30m.
