Reproduce code:
---------------
<?php
echo date_default_timezone_get(),"\n";
?>

Expected result:
----------------
The correct timezone returned, and preferably the city that has been set as the timezone for the operating system.

Actual result:
--------------
Australia/Melbourne returned, which while currently in the same timezone as Australia/Sydney, has in the past had slightly different daylight saving start/finish times.

Australia/ACT returned for a set system timezone of Australia/Brisbane, which are in different timezones, and are 1 hour different during daylight saving.
