TimeIn this zoneUTC Add a zone Write the time as 2026-08-21 09:30\. Seconds and time zones in the field itself are not read, because the zone is chosen beside it. ## Questions Is daylight saving handled?+ Yes, by the IANA database your browser ships. That is also why a zone is named as a place rather than an offset: Europe/London is the rule, and +00:00 is only what it happens to be today. Why is the reading taken twice?+ Because a wall-clock time near a daylight saving change is ambiguous. The first pass guesses an offset and the second corrects it with the offset that actually applies at that instant. How should I write a time for a team?+ In UTC, with the local time in brackets. A message that says 09:00 without a zone is read wrong by everyone who is not sitting next to you. Is GMT the same as UTC?+ Close enough for a meeting, not for a system. UTC is the atomic standard everything is defined against; GMT is a time zone that happens to sit on it in winter and moves to BST in summer. Write UTC in logs and APIs, and leave GMT to the shipping forecast. ## Related tools [Unix timestamp converterTurn a Unix timestamp into ISO, UTC and your own time zone at once, or paste a date and read the epoch back.
