Russian cities

[Paul Eggert]

Hmm, the map at <http://worldtimezone.com/time-russia2.htm> seems to
be quite closely related to <http://wwg.lgg.ru/russia/timezone.html>.
I wonder where the map is coming from originally?

Also, the two maps disagree about
Ul'yanovskaya oblast' <http://wwg.lgg.ru/russia/reg73.html>,
Altajskij kraj <http://wwg.lgg.ru/russia/reg22.html>,
and Respublika Altaj <http://wwg.lgg.ru/russia/reg04.html>.
Worldtimezone.com says the first is at UTC+4 and the other
two at UTC+7; LGG.ru says UTC+3 and UTC+6 respectively.

Do you know which of these two maps is more up-to-date and correct?
I'd guess the Russian-language one, but I could well be wrong.
