Description:
------------
When I create DateTime object using UTC and then switch to timezone
with DST eg. 'Europe/Warsaw' and i set Year to any after 2038 the DST
doesn't work.

like below: in may Warsaw is in GMT+2 time zone so when i set UTC time
to 12:00:00 time in Warsaw should be 02:00:00 (14:00:00)


Reproduce code:
---------------
        date_default_timezone_set('Europe/Warsaw');
        $gmt = timezone_open('UTC');
        $eu = timezone_open('Europe/Warsaw');
        
        $date = new DateTime('2040-05-05 12:00:00', $gmt);
        echo $date->format('d-m-Y h:i:s') . '(' .
$date->getTimezone()->getName() . ')<br>';
        $date->setTimezone($eu);
        echo $date->format('d-m-Y h:i:s') . '(' .
$date->getTimezone()->getName() . ')<br>';
        $date->setTimezone($gmt);
        
        $date = new DateTime('2000-05-05 12:00:00', $gmt);
        echo $date->format('d-m-Y h:i:s') . '(' .
$date->getTimezone()->getName() . ')<br>';
        $date->setTimezone($eu);
        echo $date->format('d-m-Y h:i:s') . '(' .
$date->getTimezone()->getName() . ')<br>';
        $date->setTimezone($gmt);

Expected result:
----------------
05-05-2040 12:00:00(UTC)
05-05-2040 02:00:00(Europe/Warsaw)
05-05-2000 12:00:00(UTC)
05-05-2000 02:00:00(Europe/Warsaw)

Actual result:
--------------
05-05-2040 12:00:00(UTC)
05-05-2040 01:00:00(Europe/Warsaw)
05-05-2000 12:00:00(UTC)
05-05-2000 02:00:00(Europe/Warsaw)
