How it works

The time you enter is read as a wall-clock time in the From zone. Using the browser’s built-in Intl time-zone database, the tool works out that zone’s UTC offset at that moment (accounting for daylight saving) to pin down the exact instant, then re-formats that instant for the To zone and a set of major cities. Everything happens on your device — no clock server is contacted.
