Because of this issue, this computer system may not be in compliance with the network administrator’s requirements, and users of this system may not be able to use some functionality on the network. Windows will periodically attempt to retry this operation, and it is possible that either this system or the domain controller will correct the time settings without intervention by an administrator, so the problem will be corrected.

A network administrator may be required to resolve the issue if correcting the local time settings does not address the problem."

The odd thing is that the samba DC time is perfectly in sync with the two Windows DCs. I setup NTP on it, and lsof reveals that the signed socket is indeed being read by samba. I am not having any other authentication issues with kerberos.

No, it is not, sorry.
Please file a bug with network captures etc.
