The relevant parts of the mentioned message:

>> Kemerovo oblast' (Kemerovo region)- in Russia will change current time zone on 
>> March 28, 2010:
>> from current Russia Zone 6 - Krasnoyarsk Time Zone (KRA) UTC +0700

That decree actually just mentions "fifth time zone", like Alexander

the zone is called "Omsk Time" with the following two finds:
