The handling of the time signal in Cockroach is motivated by the fact that in
Spanner, the target consistency is linearizability, so unrelated transactions must
commit with (database) timestamps whose ordering reflects the order of their
commit timestamps in absolute (i.e. your wrist watch) time. For that to happen,
Spanner basically just "waits" out the clock skew when committing a transaction
(prior to returning to the client). Since they do that, they go to great
lengths to synchronize their clocks and have a good grip on the actual maximal
possible offset.
Cockroach only shoots for serializability (though we do offer linearizable, if
