Ok, I have a variable ($incubation) set as 04:00:00.
Then I have another variable ($starttime) set to the current time.
Both are printing out fine.
But I'm trying to get an $endtime from adding the incubation time to the start time.
$incubation = $row['incubation']; //IM GRABBING THIS TIME FROM THE DATABASE. It prints 04:00:00 $starttime = date("H:i:s"); //prints 16:23:39 $endtime = date("H:i:s", $starttime+$incubation); //prints 20:00:00 when it's suppose to print 20:23:39
