Nope. You make sure ntp's not running, do that *once*, then fire up service ntp.
Several things: try putting into your /etc/ntp.conf, AS THE VERY FIRST LINE,
tinker panic 0
This will keep ntp from having heart failure if the jump's too large.
And I know you're on Xen, but you might see if they have something similar to
VMWare's Timekeeping best practices for Linux
