Most zones in the Russian Federation are subtracting one or two hours as of 2014-10-26. Update the meanings of the abbreviations IRKT, KRAT, MAGT, MSK, NOVT, OMST, SAKT, VLAT, YAKT, YEKT to match. The IANA timezone database has adopted abbreviations of the form AxST/AxDT for all Australian time zones, reflecting what they believe to be current majority practice Down Under. These names do not conflict with usage elsewhere (other than ACST for Acre Summer Time, which has been in disuse since 1994). Accordingly, adopt these names into our "Default" timezone abbreviation set. The "Australia" abbreviation set now contains only CST,EAST,EST,SAST,SAT,WST, all of which are thought to be mostly historical usage. Note that SAST has also been changed to be South Africa Standard Time in the "Default" abbreviation set. Add zone abbreviations SRET (Asia/Srednekolymsk) and XJT (Asia/Urumqi), and use WSST/WSDT for western Samoa. Also a DST law change in the Turks & Caicos Islands (America/Grand_Turk), and numerous corrections for historical time zone data.
