How it works
The table lists actual UTC offset transitions in the pinned IANA dataset, not a guess based on current summer/winter labels. Non-seasonal legal changes can also appear. Future rules may be revised by governments.
Uses your device clock and pinned IANA time-zone rules. This is not a certified atomic-clock service.
Important limitations
Time-zone rules can change. Your device clock and the displayed rules version affect results.
