I don't know exactly what you're asking, but I can give you some information about the timers.
ROBOTC has 4 timers: T1. T2, T3, and T4. You can access the value of the timer like this:
You can reset the timer (set it's value to zero and start it) by using ClearTimer(T1); again, you can use any of the four timers.
A word of warning when using timers: the value of the timer will automatically reset and start from zero when the timer's value reaches 32,767. That's about 32.7 seconds if you're counting in milliseconds, so if you want to count times longer than that, you need to account for this "wrap around" in your code.
Hope this helped in what you need to do.
