List of tz database time zones

This is a list of tz database time zones derived from the file zone.tab from the 2010e edition of the database.

That table has the following four columns, which are mapped into columns 2 - 5 in the list shown below:

1. ISO 3166-1 alpha-2 country code (c.c.).
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.

Not present is the prescription of start and stop of a DST, and historical changes of such a prescription.

The table is sorted first by country, then an order within the country that (1) makes some geographical sense, and (2) puts the most populous zones first, where that does not contradict (1).^[1]

Columns marked with * contain the official data from the file zone.tab version 8.33 in tzdata2010e.tar.gz taken from ftp://elsie.nci.nih.gov/pub/.
