I don't think Asia/Tomsk should be added to zone-now.tab, in this
situation. It is *born* as a "historical purposes" zone, and should
never be presented as an option for someone configuring a new system and
not caring about historical timestamps.

Basically (to put it on grounds I am more familiar with), if some county
in northwest Indiana switches from Eastern to Central time, as they are
wont to do, the new zones are created for people who care about
historical timestamps, but for people who don't they should simply
switch from America/New_York to America/Chicago without ever glancing at
the America/Indiana/* directory.
