Note Submitter: sweet_machine2000 at yahoo dot com ---- I was having problem in adding (h:i) format. i use the following codes but it turns out wrong. date_default_timezone_set('UTC'); $hours_diff = strtotime("02:00:00")+strtotime("01:00:00"); echo "<br>". date('h:i', $hours_diff); for adding: output: 08:31 date_default_timezone_set('UTC'); $hours_diff = strtotime("02:00:00")-strtotime("01:00:00"); echo "<br>". date('h:i', $hours_diff); for subtracting output: 01:00 I want the output to have a colon but im having a hard time doing it.
