From Paul Eggert:
Also, the two maps disagree about Ul'yanovskaya oblast' <http://wwg.lgg.ru/russia/reg73.html>, Altajskij kraj <http://wwg.lgg.ru/russia/reg22.html>, and Respublika Altaj <http://wwg.lgg.ru/russia/reg04.html>. Worldtimezone.com says the first is at UTC+4 and the other two at UTC+7; LGG.ru says UTC+3 and UTC+6 respectively.
In my email dated 2001-06-13 a couple of Russian language timezone lists are mentioned. These lists say: * Ul'yanovsk, in the Ul'yanovskaya oblast' - timezone Moswow + 1 (UTC+4 in winter) * Barnaul, in the Altajskij kraj - timezone Moscow +4 (UTC+7 in winter) * Gorno-Altaijsk, in the Respublika Altaj - timezone Moscow +4 (UTC+7 in winter) Worldtimezone.com gives the same information. See for one of those lists e.g. http://www.mark-itt.ru/Collection/Russia/tz_rus.html By the way, these lists say Azerbajdzhan, Kazakhstan, Tadzhikistan, Turkmeniya and Uzbekistan don't do DST. But, worldtimeserver.com says Azerbajdzhan and Kazakhstan (3 zones) do obey DST, while Tadzhikistan, Turkmeniya and Uzbekistan do not, which is the same information the tz-database gives. There is another discrepancy between lgg.ru and worldtimezone.com. According to lgg.ru the Arkhangel'skaya oblast' consists of the mainland part, the island Novaya Zemlya and the islet Kolguyev, all within the same timezone as Moscow. Worldtimezone however puts Kolguyev in the Moscow zone and Novaya Zemlya in the Moscow+1 zone. Hmmm, it's very difficult to get some definitive answers! Regards, Oscar van Vlijmen 2001-08-26
