So reverting that Tom> commit was never on the table. Exactly. But that means that if the combination of our arbitrary rules and the data in the tzdb results in an undesirable result, then we have no real option but to fix our rules (we can't reasonably expect the tzdb upstream to choose zone names to make our alphabetical-order preference come out right). My commit was intended to be the minimum fix that would restore the pre-2019a behavior on all systems. -- Andrew (irc:RhodiumToad)
