Is he using a virtual system? Is that loss constant ( or is it sometimes
1 sec, sometimes 3 sec sometimes nothing). He is eitehr running a
virtual machine, in which case he should not be using ntpd, or his
operating system is doing an attrocious job of setting the system time
rate of his clock.

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.

Cheers,
David
