The following maps show the oblast' Kirovskaya, Saratovskaya, Volgogradskaya and Astrakhanskaya to be on GMT+4 ... Oscar is correct that since 2001 these were no longer on GMT+4 but had returned to GMT+3, but this return we have not documented with one or several timezones.
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.
