Yep. Manual at http://hu1.php.net/manual/en/datetime.construct.php says:

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
PHP's date time handling auto-corrects wrong date/time values. This is similar
to doing:
<?php
$n = new DateTime("2013-04-31");
var_dump( $n );
?>
class DateTime#1 (3) {
public $date =>
string(19) "2013-05-01 00:00:00"
public $timezone_type =>
int(3)
public $timezone =>
string(13) "Europe/London"
}

Description:
------------
Europe/Budapest timezone offset is +1, and +2 in DST.
Transition to DST is at 2013-03-31 01:00:00 UTC/GMT.
According to this, locale time should not exists between 02:00:00 and 03:00:00,
and must not be accepted as valid time.
Test script:
---------------
try {
$wrong_date = new DateTime("2013-03-31 02:30:00", new
DateTimeZone("Europe/Budapest"));
} catch (Exception $e) {
echo $e->getMessage();
}
print "Wrong date in local timezone: " . $wrong_date->format("Y-m-d H:i:s");
$wrong_date->setTimezone(new DateTimeZone("UTC"));
print "<br />Converting to UTC: " . $wrong_date->format("Y-m-d H:i:s");
$wrong_date->setTimezone(new DateTimeZone("Europe/Budapest"));
print "<br />Converting back to locale timezone: " . $wrong_date->format("Y-m-d
H:i:s");
Expected result:
----------------
Get an exception.
Actual result:
--------------
Wrong date in local timezone: 2013-03-31 02:30:00
Converting to UTC: 2013-03-31 01:30:00
Converting back to locale timezone: 2013-03-31 03:30:00
