Novosibirsk Time
Novosibirsk Time was historically MSK+4.
When Novosibirsk Oblast including the city of Novosibirsk changed to MSK+3, the MSK+4 time started to be called Krasnoyarsk Time.
In 2016, according to the Federal Law ФЗ-216 signed by president Putin on July 3, 2016 the Novosibirsk Time returns to MSK+4.
The law takes effect July 24, 2016 at 2:00.
The clock will need to be set an hour ahead - that is, 3 o'clock in the morning.
