New description:

 There seems to be a bug where directory authorities take a while to update
 relays' Tor versions:
 https://lists.torproject.org/pipermail/tor-dev/2018-January/012786.html

 ~~In the Overlap table, let's mark versions as "In Vote And Consensus" if
 the vote matches the consensus, "Only In Vote" if the version is present
 and does not match the consensus, and "Only In Consensus" if the version
 does not match the consensus.~~

 Unfortunately, consensus-health does not load descriptors, so we can't
 check the actual version reported by the relay.

Comment (by teor):

 Ok, let's use timestamps. They will be more generally useful.

 I'm not sure how to populate the Overlap table. Maybe use the most common
 descriptor timestamp as the "consensus"?
