Timer in C

[FRENIKA0]

I am working with a touchpanel. As of now, whenever I press the panel, a LED lights. And as soon as I raise from the panel, the LED goes off. Well, I want to set up some type of timer or wait sequence within my code to where when I press the touch panel, the LED lights for a specified number of seconds. BUT even if I raise up off the panel, the LED will still be lit for that specified number of seconds..

To put more clearly... [As of now] Person A presses the touch panel and the LED is only lit while the person's finger is on the panel..

[Ideally] Person B presses the touch panel and the timer sequence for the LED start and even though Person B lifted its finger off of the panel, the LED will still be light for the specified amoount of time.

Any help with this will be greatly appreciated...

Some toying with the clock function should do the trick.
