The ntp server needs to be able to talk to some server on the network

ntpq -p on each of the hosts will see how they are keeping time.
Well it looks like SL-7 does not use ntp, it uses "chrony" instead and
it apparently was not running, at least I had to systemctl restart
chronyd|and then |systemctl enable chronyd to start it running. Then it
began to show signs of life. Before that all the values reported were zero!

Only the servers are blocked from the internet since I figured they
didn't require a connection but now the question of time synchronization
arises. In fact my internet connection is derived from a satellite
connection which has a system delay on the order of 800 ms. I would
think that would offset me from the rest of the world by nearly one
second if it matters ...
Interesting thought,
Bob
