Or are they expecting authentication and > refusing connections? The answer seems pretty straight forward to me, in fact it is written in the error message, ntpd is trying an IPv6 connection to that very server. Usually, it will start trying IPv6 if it finds an v6 IP address for a given server, and if the v6 connection does not success, it will try v4 connection. It would be instersting to see the answer of a dig for that time server with IPv6 address, just for confirmation, please run a: dig that.time.server ANY and see if you get a AAA reccord in the answer section.
