What I don't know, when I find these, is which ones to keep and which ones to drop.
Oh, I see. That problem is easy to solve if one of the timezones is listed in zonenow.tab; just use that timezone. But you do have an issue if none of them are in zonenow.tab.
How about if you create an auxiliary table with estimated populations of each timezone. That would let you choose which one to keep among several candidates, none of which are in zonenow.tab.
You'd then need to maintain that table, and deal with the problem we've already run into in TZDB where a timezone becomes #1 in population but people are used the old #1 (atop the problem I mentioned earlier when the definition of "now" changes as time passes). But as long as you're willing to do the maintenance that should be good enough (though not "perfect", as I keep saying...).
