Xen DomU server different time zone

I am in the testing stages of Xen right now and have discovered that you only need to run ntp on the Dom0 host. The DomU hosts get updated from the Dom0 server. What if you want to run a DomU in a different time zone?

For a RHEL 4/5 DomU edit /etc/sysconfig/clock and set the appropriate timezone OR create a symbolic link in /etc called localtime that points to the time zone desired.
