What I will do is explain in the documentation why the units are not
mentioned.
Can we remove the division in *nix also ? If ms resolution is not
supported, then why divide the us/ns ? It serves no purpose, if
rollover and unit size are not guaranteed.
I think it should be removed.
GetTickCount is a windosism.
It should give the result in ms or not be provided at all.

If you want more resolution/precision use something else (if available).
For what I do GetTickCount is perfectly fine (as long as it gives the
result in ms and it has a resolution around 10ms).
What is a travesty is the "emulation" of GetTickCount64 with
GetTickCount for the windows versions where GetTickCount64 isn't
available. *That* will produce problems with the unexpected rollover to
0 after 49 days.
It doesn't help that GetTickCount has been marked as deprecated (and
there the rollover isn't a problem because it is expected and you know
you cannot time events longer than 49 days).
