Current: tzdata2012c/zone.tab Europe/Volgograd Moscow+00 - Caspian Sea tzdata2012c/europe # Astrakhanskaya oblast', Kirovskaya oblast', Saratovskaya oblast', # Volgogradskaya oblast'. ... Zone Europe/Volgograd Propose: zone.tab Europe/Volgograd Moscow+00 - Astrakhan, Kirov, Saratov, Volgograd Reasoning: "Astrakhan, Kirov, Saratov, Volgograd" refers to federal subjects (1st level country subdivisions), while "Caspian Sea" to a lake only. According to http://en.wikipedia.org/wiki/Federal_subjects_of_Russia The federal subjects of Russia that are bordering the Caspian Sea are 05 Dagestan 08 Kalmykia 20 Chechnya 30 Astrakhan Dagestan, Kalmykia, Chechnya according to the europe file are located in Zone Europe/Moscow. Only Astrakhan is contained in both groups (Caspian Sea neigbor, Zone Europe/Volgograd member). So Caspian Sea in the comment column is not only imprecise but actually misleading. The comment for Europe/Moscow in zone.tab is Moscow+00 - west Russia a comment that does not list Dagestan, Kalmykia, Chechnya. Therefore a reader could not deduct that these three, out of four Caspian Sea neighbors among the federal subjects, don't belong to "Moscow+00 - Caspian Sea". -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
