6ms is not a high offset.  In particular, it is rather lower than you 
would expect with w32time, and better than the resolution with which 
ordinary Windows applications can obtain the time from Windows.  (Also 
offset is not the same as clock error, and, in the stable state, is 
considerably larger than that).

That's quite old.  I'm not sure that it has all the hacks to improve 
performance on Windows.

These minpolls and maxpolls will compromise the ability to smooth over 
offset variations.  Why are you not using the recommended ones?
