Monitoring of the cluster and the application server (which is also a
time server source) is limited. We currently are having application-
level issues because the cluster members are getting outside an
acceptable jitter range among each other and with the application
server. My take-away from your response if that this is a good thing
to do.

Thank you for feedback.
