starting and stopping timer using external inputs interfaced with labview

[move]

hello,

I have trouble finding how to start and stop the timer using external voltage or current pulse. we are interfacing a circuit to labview. so for that we need to count the time it takes between the two external voltages. We have to keep on comparing the voltages to some reference voltage. And when the external voltage crosses the reference voltage we have to start the timer and again we have to stop the timer using tha same logic. We need it for time calculation between the triggers.

hope you can help.
