Time Script dependant on Internal Clock Needed

I could use a time system that is dependant on the internal clock of the computer, not sure if this is possible with ruby alone or if you would need an extra .dll file to input this kind of functionality. A good example of what I'm looking for is a time script that works like Pokemon Crystal's time system. I've done some searching and couldn't find anything relevant, thanks for your time.

Thanks Diretooth, to bad I can't test the script out as my power supply failed on my desktop. Will check this script out when I get a new Desktop.

Okay, I hope you get it swiftly.
