I think what you are seeing is the "invalid field in DHCP response" message is being logged by the Superhub before the device has established date/Time. That's logical as in order to query a time server it needs an IP address. Since this is a message about the DHCP response the fact it hasn't establish other comms a that point is what you would expect.

Once it has an IP address the next thing it appears to do is query the time servers to establish Time of Day and you are seeing that logged as the next message. Quite why it reports that with an error code at level Critical though is surprising - I'd have thoguth it would be logged as Informational.
