Re: Adding a relative amount of time to an absolute time.

Hi Richard, I looked around a bit and it does seem clunky to convert a HH:MM:SS string to a DateInterval object. Why not store the buffer time as seconds only, and then do something like $date = new DateTime($event_datetime); $date->add(new DateInterval('P'.$buffer_time.'S')); echo $date->format('Y-m-d') .
