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

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 <link xlink:href="&url.maxmind.fips;">&url.maxmind.fips;</link>
for a detailed list of FIPS 10-4 codes.
</para>
