Description:
------------
If you're using a timezone, like Europe/Paris, with summer and winter times,
you
will obtain a wrong result when adding and subtracting a time interval on a
date
at summertime threshold.
I fixed that issue by making all operations on GMT timezone.
Test script:
---------------
date_default_timezone_set('Europe/Paris');
/*
Get a time just on the threshold
*/
$d = new DateTime("2012-03-25 03:00:00");
echo $d->format(DateTime::RFC2822) . "\n";
/*
Substract one hour
*/
$i = new DateInterval("PT1H");
$d->sub($i);
echo $d->format(DateTime::RFC2822) . "\n";
Expected result:
----------------
Sun, 25 Mar 2012 03:00:00 +0200
Sun, 25 Mar 2012 01:00:00 +0100
Actual result:
--------------
Sun, 25 Mar 2012 03:00:00 +0200
Sun, 25 Mar 2012 03:00:00 +0200
