Thanks for your thoughts, Bill.  No, this is a real PC, which used to work 
correctly.  There is a question as to (a) whether the PC has become 
faulty, (b) whether something had changed in the software, or (c) whether 
some other program is interfering with the time.  Nothing is supposed to 
have changed in the software, and there are no restore points early enough 
to check (b).  The obvious candidates for (c) are not present, which 
leaves (a) as the obvious cause, but I has my doubts that a PC would 
suddenly start to lose 1 second every ten minutes.

I don't know whether the loss is constant, as with NTP running it keeps 
resetting, and investigations are continuing.  It's at the point where I'm 
running out of ideas, so I may, very reluctantly, ask Dave H to get 
involved, if the current tests prove unsuccessful.  These tests are now to 
try and run as plain an NTP as possible, but a more recent version 
(4.2.6p4).  I'll post the outcome here.
