Very unlikely.  Locales struggle just to handle daylight saving
transitions, and they're allowed (practically encouraged) to ignore
*historic* DST transitions (anything before 1970).  Though to be fair,
DST transitions were extremely localized back then, and the locale
maintainers want to avoid having hundreds of tiny little locales for
the United States alone.
