Do you really get a stand-alone CEC or are your LPARs placed on one of the 
outsourcers machines? 
If so, they will probably have STP and provide a reliable time. 
And of course Gil is right: if not, you can configure STP to a timeserver to 
keep your time accurate.

It's being configured that way by our outsourcer, we no longer have 
control over the configuration. I agree with you, but wanted to see if 
there's any additional risk to our environment in this configuration.
