Netcode dev here. Predicting the clock is a trivially solved problem. The client and server know the latency between each other, the server can offset the timestamp on the input from the client to compensate for this difference, and the client can offset it's rendering of the clock data from the server. The same techniques used in regular online gaming would apply here. The only X factor here is the impact of the client lieing about its latency to the server, perhaps that could have an impact, not sure.
