Generally speaking, no.  If the history is different between Novosibirsk
and Almaty (as we have), then we retain both zones for historical
conversion purposes.

If the data we have is wrong, that's another matter.  We currently have
Novosibirsk as observing UTC+7 year-round since March 2011.  If they
switched back to UTC+6, do you know when they did so, or have any news
reports documenting the change?
