Firstly, 8:21:00 will be interpreted as 8AM unless you specified otherwise using DateTime::createFromFormat().

To work out time differences, use DateTime::diff():

$to = new DateTime("2008-12-13 10:42:00");
$from = new DateTime("2008-12-14 8:21:00");

$stat = $to->diff($from); // DateInterval object

echo $stat->format('%Hh:%Im');

This will display the hour/minute difference between the two times, but only up to 24 hours.

If you need more than 24 hours, you should do the following:

$hours   = $stat->days * 24 + $stat->h;
$minutes = $stat->i;

printf('%02sh:%sm', $hours, $minutes);

This one also does not return correct value when there is more than 24 hours between dates – dev-null-dweller Oct 21 '12 at 22:59
The $stat object is an instance of [DateInterval](http://au.php.net/DateInterval), check the docs on how to extract days/months/years. – noetix Oct 21 '12 at 23:01
So please remove/edit `format` line since it does not include any info about days and produces misleading result. – dev-null-dweller Oct 21 '12 at 23:05

First of all you need to include AM and PM in your date strings, otherwise 2008-12-14 8:21:00 will be interpreted as 8:21 AM

Now the difference between two dates is 2019 that is 33h:19m, you cant' have t with standard date formats, since they support only 24h clock. You should keep $stat as integer, and display it with sprintf like like this:

echo sprintf('%02dh:%02dm', $stat/60, $stat%60);
