Could someone help me start on writing a countdown timer?

Hi
I am making a test taker. I need to put up a countdown timer, and I haven't a clue how. Could someone please help me start. I google it and all I see is readymade scripts that can be downloaded. I'd like to write the code myself. I dont understand how I can get it to count down all by itself.
Thanks,
Hanaa

If you are not sure where to start, then you could start by reading and trying to understand the scripts that others have already written for it.

P.S I would use Javascript for these kinds of things.

And the links that might help you for the same are:
setTimeout()
innerHTML

Thanks for those. And I'll try using javascript.

Also look at the setInterval method (as a alternative to setTimeout).
