Kamchatka Time or Petropavlovsk Time (PETT; Russian: камчатское время, kamchatskoye vremya), also known as Anadyr Time (ANAT), is a time zone in Russia, named after the Kamchatka Peninsula. It is 12 hours ahead of UTC (UTC+12:00) and 9 hours ahead of Moscow Time (MSK+9). This time zone is used in the two easternmost regions of Russia after October 2014 and was also used before the time zone reform of 2010.
On March 28, 2010, while most regions of Russia switched to Summer Time moving the clocks one hour forward, the two Russian regions using Kamchatka Time, Kamchatka Krai and Chukotka Autonomous Okrug, retained UTC+12:00, effectively joining Magadan Summer Time. No further changes of the time offset occurred since. Until 2014 DST was standard in Russia around the year. When time in most of Russia was moved one hour back in October 2014, a separate MSK+9 time zone was reinstated, but the Summer/Winter time transitions didn't return.
