If you're running it on the local machine, you can check the configured timezone.

There are a lot better and more reliable methods then trying to guess timezone using GeoIP. If you're feeling lucky, try: http://www.php.net/manual/en/book.geoip.php

$region = geoip_region_by_name('www.example.com');
$tz = geoip_time_zone_by_country_and_region($region['country_code'],
                                            $region['region']);
