PHP 5.4 Can't Determine Time Zones on its own

Question

I\'m just looking for a little clarification on this. PHP 5.4 eliminated the TZ environmental variable and the \"guessing\" that date_default_timezone_get used

Answer 1

This is just a wild guess. Could you be able to get the timezone with:

date('H', 0); or something like that? I mean since the unixtime stamp is the same in all regions but the Hour differs, shouldn't you be able to base on the hour know which timezone is used?
