This isn't exactly working.. not too sure why. Although the basic concept behind this is:

1) Convert both times to their UNIX timestamp
2) Add together
3) Output as a time.

I came up with this:

Code:

<?php
$c1 = "29:00:00";
$c2 = "05:10:00";

$Newc1 = mktime($c1);
$Newc2 = mktime($c2);

$NewTime = $Newc1 + $Newc2;

echo date ('G:i:s', $NewTime);

?>

- although it's not working exactly?

Actually Tristanperry is on the righ track but there are several arguments for the mktime function:
http://php.net/mktime
Basically you need to split your string and extract hour, minute, second and pass these arguments to mktime

Ah good point.. so the string needs to be exploded..

Code:

<?php
$c1 = "29:00:00";
$c1 = explode(':', $c1);
$c2 = "05:10:00";
$c2 = explode(':', $c2);

$Newc1 = mktime($c1[0],$c1[1],$c1[2]);
$Newc2 = mktime($c2[0],$c2[1],$c2[2]);

$NewTime = $Newc1 + $Newc2;

echo date ('G:i:s', $NewTime);

?>

Something like that... wait, what are the original times formatted as?

29:00:00 - is that Hours : Minutes : Seconds

Like a stop-watch or something? What are you intending to actually get by adding

29:00:00 to 05:10:00?

As tristanperry asked is that days, hours and minutes or maybe hours, minutes and seconds it could also be minutes, seconds and milliseconds.

It may sound pedantic but it is vital information if you want some help. For example if it is the 1st option then the following is the maximum possible:-

364:23:59

with the second the following shows the maximum digits:-

23:59:59

and in the 3rd:-

59:59:999

of course the 1st digit in each may not make a difference but would of course depend on your usage.
