Description:
------------
When adding an interval to a DateTime object in european summer time and the resulting date is in
european winter time, an additional hour is added.
Please note that we stay in summer time(+2) until 3:00:00 and then the clock is set to 02:00:00
winter time(+1).
Test script:
---------------
$date = new DateTime(
'2013-10-27 01:45:00',
new DateTimeZone('Europe/Berlin')
);
$oldStamp=$date->getTimeStamp();
$interval=new DateInterval('PT15M');
echo $date->format('c')."\n";
echo $date->getTimeStamp()."\n";
$date->add($interval);
echo $date->format('c')."\n";
echo $date->getTimeStamp()."\n";
echo $date->getTimeStamp()-$oldStamp;
Expected result:
----------------
2013-10-27T01:45:00+02:00
1382831100
2013-10-27T02:00:00+01:00
1382835600
4500
Actual result:
--------------
2013-10-27T01:45:00+02:00
1382831100
2013-10-27T02:00:00+02:00
