There is currently a bill to change time in Volgograd oblast from Moscow time to Moscow+1. The bill is the result of a local referendum, so it will likely be passed into law. That would require changing Europe/Volgograd from UTC+3 to UTC+4. Proposed change date (2018-10-28) though looks too optimistic (publication of the law before that date while still possible is unlikely) and will likely be amended. http://sozd.parliament.gov.ru/bill/452878-7 Other news: The bill to reintroduce Julian calendar awaits its rejection for some time already: http://sozd.parliament.gov.ru/bill/194304-7 The bill to move clocks 1 hour forward ("permanent summer time") throughout Russia was recently recommended to be rejected: http://sozd.parliament.gov.ru/bill/383137-7 Russian Railways announced that they are changing time displayed on station clocks, timetables and tickets from Moscow time to local time: http://eng.rzd.ru/newse/public/en?STRUCTURE_ID=15&layer_id=4839&id=107332
