My guess here is you mean that the clock hasn't been set, based on your example. Might be best just to say that if a clock isn't stratum 1 or 2 (or something) NTP sourced than validation should be postponed. Otherwise I find it difficult to consume how a router itself will know if it's clock has a drift of over an hour. especially if its NTP source is wrong. > > Severs SHOULD provide time service, such as NTP [RFC5905], to client > routers. > Does this need to be said if you are making a MUST statement for NTP?
