Comment (by arma):

 Scenario: dizum is 65 seconds early. So it votes early, and sends a
 signature early, and most importantly, it makes the new consensus
 available early.

 So if the relay here has the correct time, and it happens to ask for a
 consensus at the 59 minute mark, then dizum has already switched over to
 handing out the new consensus, and most importantly, it sticks a timestamp
 on the new consensus that says it came from the top of the hour. And while
 all the other dir auths have accurate clocks, they send their signatures
 early (5 minutes early) for robustness. So it doesn't matter whether they
 have accurate clocks, dizum can by itself produce a consensus with a
 timestamp in the future that their signatures on it, and it can do this
 theoretically as soon as it has enough signatures from dir auths for that
 round -- i.e. 5 minutes early if it wanted to drift more.
