Known issues

After you install this update, conversion of old 2011 winter dates from UTC to local time for the affected Russian time zones uses the incorrect offset (+4 instead of +3 in the case of Russian Standard time). This issue affects the old winter dates only (January 2011 until the start of DST in 2011).
