Thanks for the report and patch.  I would be interested to see the output from 
an "NTPTime_Report 1" command gives on that system, with or without your fix, 
since that report displays the measured tick rate as well as the nominal one 
and your report implies the two were significantly different.

I did wonder whether the NTP time provider should correct for problems caused 
by an incorrect clock tick rate since it is able to detect them, but I was 
persuaded by Eric Norum not to do so.

I have made this change in CVS and added a patch to the Known Problems page.

Thanks,
