Description:
------------
When creating a DateTime from a timestamp (i.e. date('r)) it will report the TimeZone of the environment it was created in and not the timezone in the timestamp.

Reproduce code:
---------------
<?php
date_default_timezone_set("Etc/GMT+1");
$datetime = new DateTime('Fri, 07 Dec 2007 19:05:14 +1000');
echo $datetime->getTimezone()->getName(), "\n";

Expected result:
----------------
Etc/GMT-10

Actual result:
--------------
Etc/GMT+1

There is a bug here, but the expected result is not necessarily what you say it should be. Because there is no real timezone , it probably should return false.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.

The script now returns:
+10:00
(And you really should not be using the "Etc/*" style timezone identifiers.
