XML Digital Stopwatch in for FSX

I am new to the whole idea of XML gauge programming, so please bear with me if this seems like an obvious problem.I am trying to create a Davtron 803 (Kind of) I am not going to include the ability to set the clock from the gauge or any of that business, but what I do need it the ability to display Local Time, Universal Time, Flight Time, and Elapsed Time...as well as some other info. I have figured out everything except the flight timer and the elapsed time...basically a digital stopwatch. I have been looking all over the forums and have not been able to find much info on this topic. I can't seem to get my head wrapped around this issue. Any help would be greatly appreciated.I did find a post in which Arne Bartles included some code for this, but I can not figure out where in my code that should go.I would post some code, if I had anything that was even close.Charlie
