Thanks for the ideas, but I think this is a different issue, and on
further investigation perhaps it has always been there and I had not
noticed it.   I am not rebooting but am saving the VM state and then
restoring it.  Looking at the clock settings in Win 10 in more detail
it appears that it resyncs the clock only every 10 hours or so, based
on the time it currently thinks it is.  So if I save the vm and then
restore it an hour later the clock is one hour slow and will not
resync automatically for a number of hours.  Perhaps there is no way
round this other than to manually resync each time I restore.
