Thanks, Gautam.  The entries look completely normal (compared to a Windows 
Vista system I have), and in particular, the correct choice of 
interpolation scheme is being made (I left those entries above).  What I 
am /not/ seeing is any entries by NTP saying that NTP is stepping the 
time.

No, I don't expect Win-7 SP1 to make any difference.  I would check again 
for any power-saving stuff.  I would also suggest installing on another 
Win-7 PC to convince yourself  that NTP does work, and to have a base to 
compare against.

Cheers,
David
