About TRT and IST
TRT (Turkey Time) covers Turkey and is anchored to the IANA zone Europe/Istanbul. 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 TRT nor IST observes DST, so the offset between them is constant year-round at 2h 30m.
