A concrete example: "Exactly two years before McMurdo was established, blaa blaa seems to have happened there." It is reasonable to have that two years before return something reasonable in local time too.
"Local time" as in "local mean time" (in which case you need to know the longitude of "there" - and the tzdb is neither necessary nor sufficient) or "local time" as in "local time for some zone in which civil time is established" (in which case you need to know what zone that is)?
