Description:
------------
If you set a time zone for a DateTime via DateTime::setTimeZone() and
that time zone has no ID you get an error message and the time zone will
not be set.
This can lead to problems if you have two DateTime objects from a
source you do not control and want to format the second DateTime object
in the same time zone as the first.
Reproduce code:
---------------
$d1 = new DateTime('2008-01-01 12:00:00 +02:00');
$d2 = new DateTime('2008-01-01 12:00:00 UTC');
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
$d2->setTimeZone($d1->getTimeZone());
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
Expected result:
----------------
2008-01-01T12:00:00+0200
2008-01-01T12:00:00+0000
2008-01-01T12:00:00+0200

Actual result:
--------------
