Try ntpdc -c monlist
(ntpdc is uaually included in ntp distributions.)
ntpd only keeps track of the last N clients/hosts that contact it.
N is several hundred.
What do you mean by "correctly"? ntpd will return the best
time that it has. That could be wrong. ntpd has mechanisms
to discourage too much traffic from a single IP Address. I
don't know if/how they show up in monlist.
These are my opinions, not necessarily my employer's. I hate spam.
