The reason for two local ntpd servers instead of one is simply redundancy in
case one dies.  In your scenario, you first have to realize you have a drifting
server.  Having 3 servers won't help in this case.  Once you identify the drift,
you simply run a manual ntpdate against external servers and you know instantly
which of your local servers is drifting.
