Thank you all for your comments regarding my post.  I'm overwhelmed by
the generosity of your time and knowledge.

I think I might try and push for NTP on the server estate and leave
w32time as the time sync for the workstations.

We have a policy for users to switch off workstations overnight so I
would think the accuracy advantage of NTP would not be as clear cut.

Thanks again for your help.
