 [https://metrics.torproject.org/exonerator.html ExoneraTor] looks up a
 given IP address in the network statuses ''preceding'' a given timestamp.
 The idea is to say whether clients could have known about the relay at the
 given time.

 However, it's still possible that a relay disappeared between being listed
 in a network status and the disputed request being made.  With the current
 voting schedule, there's a 70-minute time window for this: votes are
 published 10 minutes before an hour and fresh until the hour is over.

 If a relay was found in the last network status preceding the given
 timestamp, we could also look it up in the network statuses published
 ''after'' the timestamp.  If it was, we're even more confident that the
 relay was around when the request was made.  If it was not, we're less
 confident and should say so.

 Priority for this ticket is minor, because this is an edge case that most
 people wouldn't care about, given that most people care about days, not
 minutes (#3230).  Also, we can rule out more errors by fixing #3231 first.

 This task is assigned to Metrics Utilities, because it's probably easiest
 to change the Java or Python version in metrics-utils first. Once that's
 done, the web version in metrics-web should be updated, too.
