Req: Countdown Timer - Easiest way please

[jokerfool]

Can someone point me in the right direction of a countdown timer. I've used the search and most of the code refers to clocks with start and stop buttons. I just want to add a simple timer ticking down, no buttons needed to reset or anything.

**Okay thanks to MetalInquisitor, I have a counter ticking down, but what if I want the ticker to be real and live, so if I close the application the ticker is still counting down, is this possible?



Thank you.
