How do I calculate the diference between two Times? GMT

It's not simple as this:
$time1=10:00:31;
$time2=12:00:00;
$diference=$time1-$time2;

there are something i forgot

Could you help me? Give a try

PHP does not recognize time in the format 00:00:00, it actually sees that as a string. What you need to do it translate the times into a recognizeable format (Unix Timestamp), do the calcuations, and then translate the result into the format you want displayed.

Example:

$time1 = gmmktime(10,0,31,1,1,2000);
$time2 = gmmktime(12,0,00,1,1,2000);
$diference=$time1-$time2; //time difference in seconds
