Starting October 26, 2014 Russia is changing its time zones again. All of Russia will move back one hour, except:

  • Udmurtia and Samara Oblast will remain on UTC+04:00 (thus reinstating Samara Time)
  • Kemerovo Oblast will remain on UTC+07:00
  • Zabaykalsky Krai will move back two hours to UTC+08:00
  • Magadan Oblast will move back two hours to UTC+10:00
  • Chukotka Autonomous Okrug and Kamchatka Krai will remain on UTC+12:00 (thus reinstating Kamchatka Time)

For example, Moscow will move from UTC+4 back to UTC+3 it used before 2011.

Annual DST changes will not be observed. Further information availble at

Please release a patch to update time zones and please include it to the next version.
