Navigating the tz database (tzdb) to find time zone entries for Ubuntu programs
Channel: Daniel Rosehill

If you've ever tried to set up a program in Ubuntu that used time zones, you may have been prompted to enter the tz entry for a particular time zone.

The tz database is a centralized database for providing standardized information about time zones to operating systems around the world. It denotes time zones, their longitudinal and latitudinal references, and offsets against daylight savings time.

You can quickly look up tz values in a Wikipedia article or download the source data which is maintained by the Internet Assigned Numbers Authority (IANA).

Today I learned: the world tz database (tzdb) is maintained and edited by Paul Eggert, a computer scientist and a senior lecturer at the University of California.
