Which timezones are supported?

Every zone in the IANA time zone database, more than 400 names such as America/New_York or Asia/Kolkata. The timezones endpoint lists them all.

What does a time lookup return?

The current local date and time, the UTC offset in effect, the zone abbreviation and whether daylight saving time is active.

How is daylight saving handled?

From the IANA rules built into the runtime, so offsets change on the correct dates for each zone without any manual updates.

Can I convert an arbitrary timestamp?

The API reports the current time in a zone. To convert a specific instant, apply the offset the lookup returns, or look up the zone again on the day in question.

What does a call cost?

1 token. The free plan covers 500 lookups a month.
