date duration fail to calculate

Hi Everyone,

I was very sad after a long way but still cannot figure out the duration between two date.
$date1="20090812 23:48:56";
$date2="20090813 00:01:37";

The output will be "001241".

I did the following tries, like print localtime(UnixDate(ParseDate("20090812 23:48:56"),"%s")); and other ways to calculate the differience, but :--(

Please advice. ThanksSmilie
