I have never thought about it before, but are timezone names like 'Europe/London' designed to not be sensitive to political changes and not have to change? It could have been Country/City or Region/Country but it's Continent/City instead. Continents or regions of the world don't change fast or due to politics (not often) and cities aren't renamed or disappear that often, so this scheme is probably a lot more stable than any that uses political entities. (Think about countries that split or rename or become occupied, the locations of cities like Sevastopol (occupation), or Juba (Sudan/South Sudan split) or Jerusalem (every controversy).)
