[tz] Re: EST5EDT should not resolve to America/New_York because they have different offsets

Formerly, EST5EDT corresponded to an imaginary time zone history; now it corresponds to the history of a documented location. For what it's worth, the name EST5EDT is present for backward compatibility for long-obsolete Unix System V platforms, and shouldn't be used in new software.

I take the OP's point to be that if we're keeping it around for System V compatibility, it ought to continue to mean what it meant on System V, whether that corresponds to any physical location or not. regards, tom lane
