Comment (by nickm):

 Hm. I think the original intention of that check was that we should look
 at the skew on connections with relays, but not on connections from
 clients.  Would this code make relays look at the time in netinfo from

 Maybe instead of router_get_by_id_digest() we should be looking at whether
 the connection started_here or not?
