DateTime::add
Derick confirmed, that the following is expected behaviour:
<?php
var_dump( date_default_timezone_get() );
$dateTime = new DateTime( '23:01' );
var_dump( $dateTime->getTimezone()->getName() );
$dateTime = new DateTime( '@1234567890' );
var_dump( $dateTime->getTimezone()->getName() );
?>
Output:
string(13) "Europe/Berlin"
string(13) "Europe/Berlin"
string(6) "+00:00"
So depending on the format you use to define the DateTime object it either receives the default timezone or not.

Like in many other date functions, PHP calculates the correct value for out-of-range input, so the constructor won't necessarily throw an exception when fed with wrong dates:
<?php
date_default_timezone_set('Europe/Madrid');
try{
$d1 = new DateTime('2009-02-28');
echo $d1->format(DATE_RSS) . "\n";
}catch(Exception $e){
echo "Invalid date: 2009-02-28\n";
}
try{
$d2 = new DateTime('2009-02-29');
echo $d2->format(DATE_RSS) . "\n";
}catch(Exception $e){
echo "Invalid date: 2009-02-29\n";
}
try{
$d3 = new DateTime('2009-02-xx');
echo $d3->format(DATE_RSS) . "\n";
}catch(Exception $e){
echo "Invalid date: 2009-02-xx\n";
}
?>
