I can sympathise with your VMWare time issues. We had some ESX Server
guests that would do a "Back to the Future" and suddenly jump into
2020.
After trawling through vmware's documentation and various message
boards, the apparent solution is to upgrade vmware tools on the guests
and enable PMI paravirtualisation (if the kernel supports it, the one
that ships with Ubuntu Gutsy does at least).
This *appears* to have solved the jumping problem, but its occurance
was so infrequent and random that I'd hold off judgement on the
effectiveness of the above solution for a while at least :)
