Retry, this didn't go through 2013-09-06, due to blocking by the time

Proposal to use 1946-01-01 instead of 1970-01-01 as cutoff point.

The concept of country in the database is based on ISO 3166 standards.

ISO at
http://www.iso.org/iso/home/standards/country_codes.htm
says: "The country names in ISO 3166 come from United Nations sources."

http://www.un.org/en/aboutun/index.shtml
says: "The United Nations is an international organization founded in 1945"

So 1946 is the first year where on 1 January the UN existed.

This new boundary would exclude to reject data improvement requests like

Rejection:
http://mm.icann.org/pipermail/tz/2010-January/016010.html

Apart from allowing easier inclusion of historic data, the new cutoff
point might be easier understandable by most users, assuming the UN is
more known than Unix.

The new cutoff point is located after WW2 end, thus inclusion of war
time offset changes is still not mandatory.
