PHP Manual: Returns the time zone for some country and region code combo

Description

string geoip_time_zone_by_country_and_region ( string $country_code [, string $region_code ] )

The geoip_time_zone_by_country_and_region function will return the time zone corresponding to a country and region code combo.

In the United States, the region code corresponds to the two-letter abbreviation of each state. In Canada, the region code corresponds to the two-letter province or territory code as attributed by Canada Post.

For the rest of the world, GeoIP uses FIPS 10-4 codes to represent regions. You can check » http://www.maxmind.com/app/fips10_4 for a detailed list of FIPS 10-4 codes.

This function is always available if using GeoIP Library version 1.4.1 or newer. The data is taken directly from the GeoIP Library and not from any database.

Parameters

country_code: The two-letter country code (see geoip_country_code_by_name)
region_code: The two-letter (or digit) region code (see geoip_region_by_name)

Return Values

Returns the time zone on success, or FALSE if the country and region code combo cannot be found.
