How can I add 15 minutes to the previous event time (timestamp) to get the next event time.
Note: This event time is not in a table.
Straight forward adding the two values will probly not provide the correct result.
I can get the correct time with Mysql addtime($time, $duration) but that
is only good if the if info is in a table.
<?php $time = "09:00:00";//timestamp hh:mm:ss $duration = 00:15:00;//enent duration hh:mm:ss $next_time = $event_time + $event_duration; ?>
