Indeed it does.  Apparently xend returns a 'start_time' field for a 
domain, which is the start time as a Unix time_t.  'xm uptime' just 
prints out the current time minus this start time.

One problem seems to be that this is saved in the image across reboots, 
so presumably it's fairly meaningless if the host machine was switched 
off for a signficant length of time.
