I suppose you could make up some iptables rules that logged connections
to the NTP ports.

e.g. iptables --append INPUT --jump LOG --protocol udp --destination-port ntp --log-prefix "firewall{NTP}:  "

But, if you have other rules generated beforehand, you'd might have to
insert rather than append.

You'd find something with lines beginning with "firewall{NTP}:" in
your /var/log/messages file for accesses to that port.
