Timezones

Date and time values can have a timezone qualifier suffix.

Note that timezone is not a datatype, one only exists as a part of another value.

Canonical form starts with a sign, followed by two-digit hour and minute offsets separated by a colon, like “-06:00” and “+02:30”. The zero offset, UTC, is written “Z”.

Non-canonical form also allows writing UTC as “-00:00” or “+00:00”.

This implementation only supports a resolution of 15 minutes, that is, only offsets at 0, 15, 30, and 45 minutes within an hour.
