Have you started daylight savings in the last few days? I've seen this
before and my theory is that when the domain is created, xend figures
out what the offset is from UTC and remembers it. If the DomU is
rebooted it uses the same offset which means if it was created before
DST started and then rebooted after, the offset will be wrong.
