ntpd spam in the system log

[The_Decryptor Veteran]

Is anybody else seeing this? I have no idea if it's due to being on a dual stack network but I get these errors constantly

I have no idea why ntpd is trying to act as a server, or why it's only complaining about IPv6 addresses (Or why it's happening every 5 minutes) I'm also seeing errors like this fairly often as well.

To say Apple's implementation of time synchronisation is broken is probably an understatement.
