Bug description:getTimestamp() affected by setTimezone() on DST transition
Description:
------------
getTimestamp() is supposed to return the time in UNIX-timestamp. To my
understanding a unix timestamp is always in UTC and not affected by the
timezone.
That is; regardless the the timezone, getTimestamp() should return the same
value
for any date. In most cases it does, but not on daylight-saving-time (DST)
transitions.
I have create a short script that illustrates the problem.
Test script:
---------------
$date1 = new DateTime("@1351382400"); // Sun Oct 28 2012 02:00:00 GMT+2
(DST)
var_dump($date1->getTimestamp()); //prints: 1351382400
$date1->setTimezone(new DateTimeZone("Europe/Stockholm"););
var_dump($date1->getTimestamp()); //prints: 1351386000
