Elapsed Time.vi is a very useful Express vi which returns the elapsed time and can be reseted. Unfortunately there is no pause function in Elapsed Time.vi ( LabVIEW 8.5 to 2009). I had been looking for the examples of pausing and continuing the time in LabVIEW, but there seems not be a simple one.
So I created this myself. It is not efficient in term of excecution time, but it is simple to be made from scratch and memorized.
Basically the shift registers are used to store the previous elapsed time. When it is in the false (run) case, the elapsed time is added to the ‘total elapsed time’. When the vi in the true (pause) case, the total elapsed time is transferred to the start time and the Elapsed Time.vi is reseted (stopped). Hope this will be helpful. 🙂

So I added the reset function for this SubVI:
