echo $datetime->format('Y-m-d H:i:s') . "\n";

$datetime->setTime(14, 55, 24);
echo $datetime->format('Y-m-d H:i:s') . "\n";

// Warning: Does not increment the hour!
// This is because the hour has been set (14) - see date_modify()
$datetime->setTime($datetime->format('H'), $datetime->format('n') + 6);
echo $datetime->format('Y-m-d H:i:s') . "\n";

// *Does* increment the day, because the day has not been set
$datetime->setTime($datetime->format('H') + 12, $datetime->format('n'));
echo $datetime->format('Y-m-d H:i:s') . "\n";
