How it works

UTC is the reference for the instant; GMT usually denotes a time zone or mean solar-time convention. They share a zero-offset display here, but are not interchangeable in every technical context. Copying returns an ISO 8601 UTC timestamp ending in Z.

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.
