Great this is what I thought, however I've just had another odd one with
2008 R2 domU. The dom0 was rebooted, and when it came up the domU was
1 hour behind the time of dom0. It had to be changed in windows to the
correct time.

Something to do with the domU being saved when the dom0 rebooted? If you
xm create the time is correct with localtime set to 1.
