Now I have tested both the GetTickCount and Now() methods.
I have synched my tests against a GPS receiver to get an accurate
reference.
Turns out that GetTickCount has a sawtooth-like overlaid timing noise
signal which is about 15 ms.
But using Now() I don't see this.
In both cases I could detect a 12 ppm drift in the clock of mt PC.
of course, by now, you've seen the post that shows that GetTickCount
uses now() as the base with which to multiply by :? ;)
That was the non-Windows implementation.
