mySQl has built in functions for adding dates or time to an existing date, so you could just use ADDTIME(date1, 1:0:0.0) but I'm not sure why if you're already directly adding the start date you wouldn't do the same for the end date like:

VALUES (5, LAST_INSERT_ID(), '2016-03-18 15:00:00', '2016-03-18 16:00:00');

Just wanted to say thank you for your help If anyone want to tknow I ended up using this code:

$inserted_time = $_POST['time'];
$bookedtime = strtotime($inserted_time) + 60*60;
$endtime = date('H:i:s', $bookedtime);
