How it works
This tool uses the Intl API’s time zone data — the same up-to-date IANA time zone database your operating system uses — rather than a hardcoded offset table, so it correctly handles daylight saving time transitions for zones that observe it.
FAQs
Does this handle daylight saving time correctly?
Yes — because it reads your browser’s built-in time zone database rather than using a fixed offset, it automatically accounts for daylight saving time rules, including that they differ by country and change over time.
