Each his opinion.

For example, I think GetTickCount is utterly useless.

I have never used it, never will and I have nevertheless already done 
plenty of time measurements.

Depending on the platform, gettickcount falls back on Now(). This does not have a
millisecond precision. This call can take a time of up to 90 ms. 
So saying that gettickcount has millisecond precision would be simply
incorrect.

What I will do is explain in the documentation why the units are not
mentioned.
