[tz] Issues about parts of Europe/Moscow in 1981/1982

[Alois Treindl]

I have the impression that some of the comments in the Russia section in 
file 'europe' have not been followed through in the actual zone tables.

I refer to the lines beginning here

# From Stepan Golosunov (2016-03-07):
# 11. Regions-violators, 1981-1982.
# Wikipedia refers to
# 
http://maps.monetonos.ru/maps/raznoe/Old_Maps/Old_Maps/Articles/022/3_1981.html
# http://besp.narod.ru/nauka_1981_3.htm

... until
# 12. Udmurtia

Also the Russian wikipedia page
https://ru.wikipedia.org/wiki/%D0%9C%D0%BE%D1%81%D0%BA%D0%BE%D0%B2%D1%81%D0%BA%D0%BE%D0%B5_%D0%B2%D1%80%D0%B5%D0%BC%D1%8F#%D0%9F%D0%B5%D1%80%D0%B5%D0%BC%D0%B5%D1%89%D0%B5%D0%BD%D0%B8%D0%B5_%D0%B3%D1%80%D0%B0%D0%BD%D0%B8%D1%86%D1%8B_%D0%BF%D1%80%D0%B8%D0%BC%D0%B5%D0%BD%D0%B5%D0%BD%D0%B8%D1%8F_%D0%BC%D0%BE%D1%81%D0%BA%D0%BE%D0%B2%D1%81%D0%BA%D0%BE%D0%B3%D0%BE_%D0%B2%D1%80%D0%B5%D0%BC%D0%B5%D0%BD%D0%B8_%D0%BD%D0%B0_%D0%B2%D0%BE%D1%81%D1%82%D0%BE%D0%BA

contains the sentence (in Google translation)

> In the autumn of 1981, Arkhangelsk, Vologda, Yaroslavl, Ivanovo, 
> Vladimir, Ryazan, Lipetsk, Voronezh, Rostov-on-Don, Krasnodar and

Shanks International atlas has similar information, and also the Russian 
book
Zaitsev A., Kutalev D. A new astrologer's reference book. Coordinates of 
cities and time corrections, - The World of Urania, 2012
Russian: Зайцев А., Куталёв Д., Новый справочник астролога. Координаты 
городов и временные поправки

To me it seems that an extra zone is needed, which starts with LMT util 
1919, later follows Moscow since 1930, but deviates from it between 1 
October 1981 until 1 April 1982.

I suggest to call this zone Europe/Yaroslavl, because Yaroslavl with a 
population of 608'000 seems to be largest city in the deviating area.
