Of course governments determine civil-time rules, and these rules 
determine what goes into tzdb. But that does not mean that tzdb must 
include Zones for Utah, Idaho, Montana etc. merely because Arizona has 
an Zone. All it means is that we need to record governmental rules 
accurately and concisely. tzdb will continue to be easier to maintain 
and use if it focuses on timekeeping, not politics.
