FAQ

Does the converter handle daylight saving time automatically?

Yes. DST shifts are handled by the browser’s Intl.DateTimeFormat and reflected in the result.

Can I convert any time zone?

The presets cover major IANA zones. If a city is missing, pick an equivalent zone (for example, Kuala Lumpur uses Asia/Singapore).

What about ambiguous or skipped times during DST transitions?

Some regions repeat or skip an hour. We show the converted time with the day shift and offset to help you confirm edge cases.

Are historical time‑zone changes supported?

We rely on the browser/OS time‑zone data. Historical rules can vary by version; verify with official sources if precision is critical.
