Timer in C# CF

Question

Hi, newbie to c# here, hoep someone can help:

I'm attempting to develop an application that uses a clock, I've found the example at http://www.c-sharpcorner.com/Code/2003/Aug/EggTimer.asp, but I don't know how to do that in the compact framework, does anyone have an example?

The application is for a smartphone, the idea is to have the timer started/stopped by the user pressing a button on the keypad.

Cheers,

Matt
