Thanks for checking.

Although that will work for today's timestamps, it will mishandle 
timestamps before October 2004, as Asia/Almaty was at +06 (with DST) 
from 1992 through 2004 whereas Qostanay was at +05 (with DST). Our 
guideline is that a new Zone entry is needed if the timestamp history 
has diverged at any time since 1970, so it looks Qostenay needs a Zone 
now (it didn't before, as this is the first time it's disagreed with 
Qyzylorda since 1970 as far as we know).
