Let's see if I've got a handle on the Russian areas of interest: Place Decree #725 tzdata211j Notes Bulunskij MSK+6 MSK+7 covered by Asia/Vladivostok Tomponskij MSK+6 MSK+7 covered by Asia/Vladivostok Ust'-Majskij MSK+6 MSK+7 covered by Asia/Vladivostok Ojmyakonskij MSK+7 MSK+8 covered by Asia/Magadan Sakhalin MSK+8 MSK+7 already separate--Asia/Sakhalin For each of these five places, the question then becomes: did the place change time zones in 2011? If so, we get to find out the exact instant when the change took place. If not, we get to correct the "europe" file (at least to the extent of changing a comment). Does anyone have any light to shed? --ado
