Vista 64 Host OS Ubuntu 9.0.4 Guest OS. The guest os clock is exactly one hour ahead of host clock. Both have right time zones set and I have turned off UTC in /etc/default/rcS file (UTC=NO). everytime i correct the date/time, after about 10 seconds, it resets the guest OS clock to be one hour ahead of host OS. I traced this problem to vboxadd-timesync. If this program is stopped, then clock stays correct. vboxadd-timesync adds one hour to guest os clock for unknown reasons.
