That's great to know, thanks.
I will speak with the manufacturer and see if a newer version can be
adopted. It's good to know that it may well be a limitation of the NTP
version being used.
Today I've been told that on newer machines I can enable the HPET (high
precision event time) in the BIOS if available and that should give a
better clock to begin with.

I will check the CPU optimisation as soon as I'm in front of one of
Thanks for your help David
