Shouldn't Kemerovo oblast' use OMST/OMSST timezone abbreviation?

[Petr Machata]

... given the time offset it could be either that, or NOVT that tzdata 
currently uses.  But Wikipedia lists Kemerovo under Omsk Time:

http://en.wikipedia.org/wiki/Kemerovo_Oblast
http://en.wikipedia.org/wiki/Omsk_Time
http://ru.wikipedia.org/wiki/Новокузнецк

One one reference outside of obvious Wikipedia copies:

Though I was unable to find anything official.
