subtarct one timestamp from another

[co0kz]

looking for a way to subtract one timestamp value from another and output the result as..

ie..

$remainingtime = $timestamp1 - $timestamp2

and then output $remainingtime as the below result

resulting in..

2 Days 10 Hours 33 Minutes 14 seconds. (example)

i know and understand how the timestamp value works but i can't figure out how i would split seconds into the above example.

I've searched both here and vb.com and done a wider search and can't seem to find how this could be done without altering core files whicvh i don't really want to do if i can help it.

Ideas on how this is acheivable would be greatly appreciated.
