List of tz database time zones

World map showing time zones from the tz database version 2013i

This is a list of time zones in the tz database release 2016f. The list is derived from the zones, links, and rules specified in zone.tab and the 7 "continent files" – africa, antarctica, asia, australasia, europe, northamerica, and southamerica. It also include other valid entries from the etcetera and backward files.

The four columns in zone.tab are mapped into columns 1–4 (marked with *) in the table below. The file contains the following comments:

# This file contains a table with the following columns:
# 1.  [[ISO 3166 2-character country code]].  See the file `iso3166.tab'.
# 2.  Latitude and longitude of the zone's principal location
#     in [[ISO 6709]] sign-degrees-minutes-seconds format,
#     either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
#     first latitude (+ is north), then longitude (+ is east).
# 3.  Zone name used in value of TZ environment variable.
# 4.  Comments; present if and only if the country has multiple rows.

The UTC offsets (columns 5 and 6) are parsed from the "continent files" and accordingly ISO 6709 are in the format {+|-}hh:mm where the sign is + for east of UTC or - for west of UTC, and hh and mm are hours and minutes, respectively. The UTC DST offset is different from the UTC offset for zones where daylight saving time is observed (see individual time zone pages for details).

The table is sorted by TZ by default.
