How long does a tick last for the Tick Count (ms) VI in LabVIEW?

Question

I'm trying to compare the timing performance between a VI implemented in LabVIEW and another VI implemented in LabVIEW FPGA module. If I use the Tick Count in both VIs (every one in their own module), I want to know how long does a tick last in LabVIEW standard (in the computer)?
Thanks

I have this doubt because I read that a tick lasts 55ms in the following source:

My tick count provides me better results than the hardware results, which is impossible because this is the same algorithm. If I consider the 55ms time, then the FPGA is really faster.

What's your opinion?
Thanks again
I think you are misunderstanding what the value of a "tick" is.  From what I gathered from reading your link (which I couldn't get to from your post, but accidentally ran into on a search) a tick of the OS clock."  Curiously, though - why 55ms?  That was mentioned as the tick of a Win95/98 OS!
I guess you can say that the it returns the value of the next "tick" of the OS clock and returns that value in ms.  So, the value of a tick varies from OS to OS.  In Windows 95/98, for example, you can only look at the OS clock every 55ms or so, but it still returns a value that represents ms.
