when does the tick count start

[karlw]

I see that the tick counter rolls over at 2^32 ms, that's 49 days.  So if the counter started when Labview or the VI starts, I would never care about the rollover. 
So when does it start?  Can I control when it starts?     I need a resolution less than 1 sec, so the second timers don't help me.
Also do other funtions or VIs continue to operate when a Wait (ms) function is running?

The tick count does not begin when you open LabVIEW or the VI. The on-line help says that the base time is undefined. There is however, no problem with you taking the tick count when you first start the VI and using that later in the VI. It's also untrue that the other time functions in LabVIEW only have 1 second resolution. They have the same millisecond resolution as tick count. If you have code in parallel with the Wait (ms) function, they will exeucte in parallel.

Also, in the future, post questions of this nature to the LabVIEW board. This board is for the NI counter/timer boards.
