World clock

A built-in major mode in Emacs that provides a world clock.

Entry point:

Run with elisp:world-clock, quit by typing q.

The (IANA) time zone database (a.k.a. tz or zoneinfo): file:///usr/share/zoneinfo/zone.tab https://www.iana.org/time-zones
Online time zone search with zoneinfo: https://time.is/

A message for the people sending “UTC offsets”:

Please, always tell your IANA time zone, so that we avoid DST and other issues. For example, Australia/Perth and not AWST (UTC+8). It is the best approach when working across time zones. If you do not know how to find your IANA time zone using your computer, use the website https://time.is/.
