Comment(by arma):
Hey, isn't the timestamp in the clienthello (and serverhello), and thus
visible to external observers too?
So a) a passive adversary of the client can do this tracking too, not just
the guard
and b) if we stop putting (something similar to) the time there, we have
introduced an "is it tor tls or other tls" identifier.
