working with dates

[graziano]

Hi

I have 2 dates in this format

$timeold = date('m.d.y H:i:s', $timeold);

$time2=(strtotime("now"));
$time2 = date('m.d.y H:i:s', $time2);

for example $timeold is 09.21.06 08:50:30

and $time2 is 09.21.06 09:00:38

When I make this
$diff= $time2-$timeold;

I receive this
-608.21000003815

how can I transform this value (-608.21000003815) in hours minutes seconds ?

THANK YOU!

$diff= strtotime($time2)-strtotime($timeold);
