Description:

DateTime::getTimestamp() returns different value from
DateTime::setTimestamp().
Problem is caused by time zone where is used daylight saving and time when
timezone offset is switched.
Test script:
---------------
$tz = new DateTimeZone('Europe/Prague');
$date = new DateTime('now',$tz);
$date->setTimestamp(1351386000);
echo $date->getTimestamp() . "\n";
$date->setTimestamp(1351386000-3600);
echo $date->getTimestamp() . "\n";
Expected result:
----------------
1351386000
1351382400
Actual result:
--------------
1351386000
1351386000
