I think that is part of the reason I'm sanity checking.  I think if the
servers stay in sync... it's probably a non issue.  But that is the issue..
I've seen the havoc when one out of two servers is bad... and with the load
balancer, there's no guarantee I'm any better off.......

**especially** considering that statement!   Hmmm....if that's the way ntpd
works, then I think the load balancer is worse than useless for ntp
clients... it could be disastrous, correct?

Thanks again for the feedback/advice... I think that re-examining the
configuration is even more important now.

I like the idea of one time server from a pool and the other from a gps
based source.
