Bug description:TLA timezone dates produce wrong results with add/diff
Description:
------------
If you diff two dates with TLA timezone (like EDT) and then add the
interval back
to the earliest date, you would not get the later date but instead the
result will
be one hour off. See example below.
Test script:
---------------
$start = new DateTime('2010-06-04 02:18:48 EDT');
var_dump($start->format('U'));
$end = new DateTime('2010-06-06 18:38:28 EDT');
$ts = $end->format('U');
var_dump($start, $end);
$int = $start->diff($end);
var_dump($int, $start);
var_dump($start->format('U'));
$res = $start->add($int);
var_dump($res);
Expected result:
----------------
.....
object(DateTime)#1 (3) {
["date"]=>
string(19) "2010-06-06 18:38:28"
["timezone_type"]=>
int(2)
["timezone"]=>
string(3) "EDT"
}
Actual result:
--------------
.......
object(DateTime)#1 (3) {
["date"]=>
string(19) "2010-06-06 17:38:28"
["timezone_type"]=>
int(2)
["timezone"]=>
string(3) "EDT"
}
