FAQ

Does it handle daylight saving?

Offsets come from your browser's IANA database, so each date uses the rules in force on that day.

Which zones are available?

Eighteen common zones covering the Americas, Europe, Asia and Oceania, plus five reference zones under the result.

Why does another app show a different time?

The zone abbreviation may differ, but the instant is the same. Compare the UTC time to confirm.
