Thanks, this problem should be addressed in tzdb release 2016j and later, which contain a new Zone Europe/Saratov covering Saratov oblast, which switched from UT +03 to +04 on 2016-12-04. Our information is that Volgograd oblast is still at +03. Please see: http://publication.pravo.gov.ru/Document/View/0001201611220031 If this is incorrect please let us know.
