I've been doing the CLD practice exams, and part of the solution to the Car Wash example contains the VI ElapsedTimer.vi. When I looked close at the underlying code, it appeared to be almost precisely like the code for the Elapsed Time Express VI, except it had the additional ability in that you could pause the timer. I am assuming that the ElapsedTimer.vi must have been part of the LabVIEW library at some point, but it doesn't appear to be there now so I am guessing they took the pause function out when they converted it to an express VI. Assuming that's the case I'm not sure why they would do that. I thought maybe it made the function non-re-entrant, but both VI's use uninitialized shift registers to hold values from prior calls, so I don't think that is the reason. It's simple enough to write a wrapper around the Elapsed Time Express VI to create a pausable timer, but I am wondering if the ElapsedTimer VI with the pause already built in is available someplace in the library and I just haven't found it. If that's not the case, does anyone know why NI took out the pause function when they created the Express VI?
