When loaded on the target laptop whose clock is local Mountain the ubuntu adjusts time -6 and  and I have managed to cluster things up using hwclock --localtime --set --date XX:XX plus copying /usr/share/zoneinfo/MST7MDT to /etc/localtime (I think I did the copy first ... I was pretty tired at the time). Anyway I also frantically

This is a little hard to follow, could you reboot and repost the
following:

1. what time does the BIOS of the host hardware say?

2. on the host OS (Linux) what is the output of:

# hwclock
# hwclock --utc

3. In your VM, running on the host, show us the values for #2's hwclock.

# hwclock
# hwclock --utc

4. output of something like /etc/sysconfig/clock (fedora/redhat)
