What is Timezone?
The timezone converter takes a wall-clock time in one IANA timezone and computes the equivalent wall-clock time in another, accounting for daylight-saving rules in both.
How it works
It converts via the UTC instant using the Intl API, which encodes the real IANA tz database including historical and DST offsets.
