Bug description: dst information lost over Year 2038
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)
