Frequently asked questions

How is the time kept accurate?

The clock uses your device's own clock and the browser's built-in IANA time zone database (Intl.DateTimeFormat), so each city shows the correct local time including daylight saving.

How does the time zone converter work?

Enter a time and pick the source city. The tool treats that as the wall-clock time in the source zone and shows the exact matching local time in every other city.

Does it need the internet?

No. All conversions run entirely in your browser with no network calls, so your data never leaves your device.
