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
