Frequently asked questions

Are zones automatic for daylight saving time?

Yes. We use the browser's IANA timezone database, so DST transitions (e.g. summer time) are handled correctly for every zone.

How accurate is the displayed offset?

It's exact for the reference time you set. Offsets change across DST boundaries — moving the reference forward an hour may shift a zone from UTC+1 to UTC+2.

Where are the zone names from?

We list IANA zone names (like 'Europe/London' or 'Asia/Tokyo'). The browser's Intl.supportedValuesOf returns its full set on modern devices.
