I have barely touched the game world, but one common thing that shows up in many games is a bar that ticks down your last moments of time. A question for a countdown timer is often brought up in forums, and there are many examples of timers kicking around everywhere from the built in behaviors to other samples on the web.
Here is a really quick one that just reduces the size of a QD (quick draw) rectangle. It used the _system.milliseconds for checking time on the exitFrame of a behavior applied to the QD rect sprite.
