Hi -
While tracking-down some fun with measuring CPU utilization under
Windows my "Windows guru" told me that while GetSystemTimeAsFileTime
returns 100's of nanoseconds since the beginning of the Windows epoch,
it is really only updated once per clock tick. Presently that is once
every 10 ms.
From poking about under msdn.microsoft.com it seems that just about
anything that returns clock time is limited to 10 ms precision, so I'm
not entirely sure there is much to be done but I thought I should
ask/mention since the online glib API docs don't seem to mention that
limitation:

Seems that GetSystemTimeAdjustment is involved in finding the precision
of clock time:

In glib's documentation's defence, the MSDN discussion of
GetSystemTimeAsFileTime:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getsystemtimeadjustment.asp
doesn't discuss the limitation either
