List of timezones and GPS co-ordinates?


I need a list of the time zones and their approx corresponding co-ordinates (LAT LONG)

If a user selects London as their time zone, I want the map to zoom out to show the UK with London in the center

It doesn't have to be exact, just a rough idea of LAT and LONG

If you want this for a commercial website you will have to pay a license but here are some resources which offer something close

However i need it the other way around
Instead of passing in a lat and long and returning time zone, i want to pass in time zone and return lat and long

or just simply have a rough set of co-ordinates assigned to each of these options:

Try the TZ database managed by Icann -  Wiki has a copy of the public domain information but you may need to do some more manipulation


# 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.
# Columns are separated by a single tab.
# 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).
