Thanks for the heads-up.
Shanks & Pottenger (2003) say Kirov is still at +0400, which sounds
incorrect to me; and that Saratov, Volgograd, and Astrakhan switched
to +0300 on 1992-03-29 02:00. Of all these, Volgograd has the largest
population, so I suppose it should get a tz entry.
I'll need to review Shanks & Pottenger, and Shanks's earlier editions,
to see how this error crept into the tz database. Also, I'm puzzled
by the disagreement about Kirov.
Here's a draft entry for Volgograd, given what I know now.
# Astrakhanskaya oblast', Kirovskaya oblast', Saratovskaya oblast',
# Volgogradskaya oblast'. Shanks & Pottenger say Kirov is still at +0400
# but Wikipedia (2006-05-09) says +0300. Perhaps it switched after the
# others? But we have no data.
