Global Time Zone Lookup

Browse global time zones, UTC offsets, current local times, regions, and Daylight Saving Time status using the Brilliance One Public API.

Time-zone information is retrieved from the Brilliance One Public API. Search filtering is performed against the returned results in the current session.

Search Time Zones 0 / 100

Search by time-zone name, region, current time, or UTC offset.

Region Region filtering requests a new result set from the Brilliance One API.

WORKING WITH TIME ZONES

Use identifiers, not fixed offsets

Prefer an actual time-zone identifier such as America/New_York instead of storing only UTC-05:00.

A fixed UTC offset does not contain Daylight Saving Time or historical transition rules.

Store timestamps in an unambiguous form and retain the intended time zone when local scheduling matters.

Time-zone and DST rules can change, so applications should use maintained time-zone data.

Be careful around DST transitions because some local clock times can occur twice or not occur at all.

ISO 8601 timestamps with an explicit UTC offset are useful for exchanging specific instants between systems.
