On Ubutu:
If you get 0.system for the version, this means you have the version that PHP shipped with. For a newer version, you must upgrade via the PECL extension (sudo pecl install timezonedb)
http://pecl.php.net/package/timezonedb
[#2] Ubuntu [2011-06-16 10:35:41]
On Ubuntu 11.04 it returns the string "0.system".
