well, you're right. It's not possible to have
independent ntp clients running in your domU's because
you only have one physical harware clock, right? ;)

It seems is possible with independent_wallclock parameter in /proc/sys/xen

And I can't really understand your argumentation about having
serveral domU's "around  the world"? In that case, don't you have
also several dom0's arrounf the world at that places?

Imagine that environment: several VPS for client who are in differents locations around the world.

A real example is: my hosts are in Spain but I've several clients in south-america; some of them want to sync their VPS with their own time, not with spanish-time.
That's not an NTP issue: that's a timezone issue. You should *NOT, NOT, NOT* use NTP to try to manipulate your local times htis way: NTP is supposed to set the hardware clock, your timezone settings then adjust the display and handling of that for your local configuration.
