Timezone

Enter a UNIX timestamp in seconds or milliseconds, or a date string, and see the equivalent time in six zones side by side: your own local zone, UTC, New York, London, Tokyo and Hong Kong. The zone list is fixed — there is no zone picker — and conversion runs one way, from the value you enter out to those six.

Conversion uses the browser IANA timezone database, so daylight saving transitions are applied correctly.

Useful for correlating log timestamps across regions or checking when a scheduled job actually fires for users in another zone. For two-way timestamp work — a running clock, seconds and milliseconds side by side, a date picker that gives you the number back — use the Epoch Converter instead.
