Need help adding seconds to time

I have time (no date) in the format: 00:00:00 and I need to add a few seconds to it, how do I do this?

Is this what you're looking for: [code]<?php
$time = '13:15:07';
echo "Time: {$time}<br />";
$new_time = date('H:i:s',strtotime($time)+8); // adds 8 seconds
echo "New time: {$new_time}";
?>[/code]

It would generate the output: [code]Time: 13:15:07
New time: 13:15:15[/code]

Thanks for the response, but this isn't adding correctly. Here is my code based on what you posted:
[code]$total2 = date('H:i:s',strtotime($_GET["score"])+$_GET["cones"]);[/code]

Scores: 00:33:26
Cones: 39
Total2: 00:34:05

Nevermind, just realized the the last number is seconds and not milliseconds. It is working correctly. Thanks for the help.
