Thanks for these examples.
What might be possible would be to support "political" links, as well as backwards compatability links, and perhaps have a rule that if there is no zone named for the capital of a country, a political link for it be created (linked to whatever is the "correct" timezone according to our rules).
I strongly second this!! If it's doable without too much hassle, please do!!
I personally don't have a problem with using political capitals for zones, as zones are altered by political decisions. However by your rules, the Canadian basis for the Mountain Time zone in Alberta should be changed from Edmonton to Calgary, as Calgary has had a larger population for the municipality, urban, and metropolitan census areas than Edmonton for years, and the difference is still climbing. Edmonton should be retained as a backward compatibility link.
