It worked fine on my setup. Is it possible that you set dom0 or domU
to use local time instead of UTC for system clock?
I set dom0 and domU to use UTC. This is the content of my /etc/sysconfig/clock :

ZONE="Asia/Jakarta"
UTC=true
ARC=false

with that setup Xen's initial value (with dom0 running ntp) is the
same as what I get when running ntp on domU.

For domUs that uses localtime as system clock, I add this setting on
domU config file:

localtime=1

You could also play with rtc_timeoffset setting (in case domUs uses
different time zones).
