Krasnoyarsk Time (KRAT) is the time zone seven hours ahead of UTC (UTC+7) and 4 hours ahead of Moscow Time (MSK+4). KRAT is the official time zone for central and east Siberian regions of Krasnoyarsk Krai, Kemerovo Oblast, Khakassia and Tuva.
Novosibirsk Oblast used this time zone until 1993 when it was known as Novosibirsk Time NOVT/NOVST. It was renamed after that.
Between 27 March 2011 and 25 October 2014, Krasnoyarsk Time was fixed at UTC+8.
