[tz] timezone Verschlimmbesserung

[Alois Treindl]

I absolutely disagree with the claim that end-user benefit of pre-1970 
data is exceedingly tiny.

*pre-1970 time data are extremely important for hundreds of authors and 
millions of users of astrological software.*

Whatever one may think of astrology, it is a fact that at was 
astrologers like Thomas Shanks and others who collected extensive
historical time zone data, pre- and post-1970.

TZ database would not be what it is without contributions and ongoing 
effort by the "astrological community".

I fully support Thomas Finch's proposal:
