Almost, it returns the full offset from *UTC*, and not *GMT*. They're
slightly different:

Description:
------------
DateTime::getOffset is said to return the DST offset in the
documentation. This sounds like it will simply return 0 or 3600
depending on whether or not DST is in effect for the given DateTime
object. It actually returns the full offset from GMT. Documentation
should better reflect this or the function be changed.

Reproduce code:
---------------
date_default_timezone_set('Europe/Helsinki');

$winter = new DateTime('2009-02-13 14:25:41');

echo $winter->getOffset();

Expected result:
----------------
0

Actual result:
--------------
7200
