History
Decree No. 725 of 31 August 2011 changed Moscow Time (MSK) from UTC+03:00, or UTC+04:00 with seasonal daylight saving time (DST), to UTC+04:00 all year. Therefore, the time zones of Sakha, which were MSK+6, MSK+7 and MSK+8, changed from UTC+09:00, UTC+10:00 and UTC+11:00 (or UTC+10:00, UTC+11:00 and UTC+12:00 during DST) to UTC+10:00, UTC+11:00 and UTC+12:00 all year. As the decree took effect when DST was already observed, there was no change in local time in most of Sakha. However, the decree also changed the offset of some parts of Sakha with respect to Moscow Time (MSK), and thus to UTC.Постановление Правительства Российской Федерации № 725 от 31 августа 2011 г. «О составе территорий, образующих каждую часовую зону, и порядке исчисления времени в часовых зонах, а также о признании утратившими силу отдельных постановлений Правительства Российской Федерации».
