Comment (by mikeperry):

 I think there is some confusion due to a recent tor-talk post that was
 stitched together based on a bunch of partial/incorrect/unrelated
 information and then ignored by reasonable people because tor-talk is
 ruled by trolls.

 If you could actually recover the current time from the ISN, that would be
 a cause for concern, since it could make correlation attacks much easier
 given a timestamp at the exit or hidden service. But I agree, it doesn't
 seem like that is actually the case.
