Python library for mapping ISO 3166-1 alpha-2 country codes to Olson timezone names.
When country-level is too coarse, you may choose from a list of timezones by coordinates: 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).
Usage example:
all_us_timezones = timezones['US'] # Returns a dict by coordinates
honalulu_timezone = timezone['US']['+211825-1575130'] # Returns 'Pacific/Honolulu'Country names are compatible with GeoIP database (for example, there's EU "country").
