 Replying to [comment:15 qbi]:
 > As I suspected the `dirreq-(read|write)-history` lines are also affected
 by this bug. I found several lines with wrong dates so far.

 Interesting!  This makes sense, because I reused the byte history code for
 dirreq histories.  Can you paste the affected relay descriptor identifiers
 here?

 I wonder if we reached the point where looking at descriptor archives
 won't tell us why there's a bug.  There seems to be no specific Tor
 version or platform that has this problem and that we could blame.

 How about we analyze the code that implements the dirreq histories and try
 to find the bug here?  If we find the bug in the code that's touched by
 dirreq histories, we very likely also find the bug in general byte
 histories.  Dirreq histories have been implemented in
 [https://gitweb.torproject.org/tor.git/commit/db94b7f46ef02d5a1de132a5b746b350f3d066b7
