And now, a simple issue with a simple solution:

https://github.com/tlswg/tls13-spec/issues/64

Consensus was to drop time from the random fields. Prohibiting non-random in ServerHello.random and adding a 4 byte uint32 ServerHello.time for TLS 1.3+ seems like a really simple solution. (note that ServerHello is already changed by dropping compression_method)

The ability of a client to sanity check or sync its time seems like something worth having, especially for only a 4 byte cost.
