FAQ

What limitations should I know?

Daylight Saving Time: Some countries/regions observe DST, which may cause a one-hour difference when switching.

When might it fail?

Browser compatibility: Timezone needs Intl.DateTimeFormat; Picture-in-Picture needs Chromium video PiP (falls back to an in-page float).

What else should I watch for?

Local time: The tool relies on your system time — ensure your computer's time is accurate.
