Comment (by teor):

 The original commit was intended to reduce linkability between hidden
 service instances on the same tor instance, rather than hide the startup
 time itself:

 commit 4b76fe8
 Author: Roger Dingledine <arma at torproject.org>
 Date:   Mon Nov 15 09:05:54 2004 +0000

     Also make sure the hidden service descriptors are at a random
     offset from each other, to hinder linkability.
