I would like to suggest that if historical zone changes can not be accomodated
in the main zone files, perhaps they should be added as zone entries in the

If we can support historical leap seconds, so that scientists can correlate past
data to the second, we should also try to support historians, genealogists,
astrologers, and others who care about past times, as well as the travel
industry who care about current and future times. Oh, and the sys admins who
care their systems show the correct time to all users, where and when ever they
