For an implementation to tolerate Byzantine faults, it needs a clock synchronization algorithm that can tolerate those faults. When I arrived at SRI, there was a general feeling that we could synchronize clocks by just having each process use a Byzantine agreement protocol to broadcast its clock ...
not necessarily clock synchronized, and they do not arrive in the same order they are generated. Nevertheless, log information has to be coherent in time to be useful. To support the events we propose to use Lamport’s logic clocks, originated at different sources, in a causal relationship. ...
