Allowing anyone to register timezones will mean that no one will trust the registry. It must be a clear who is in charge of or defining the registry information.

Interesting, but that is not the way it works. Any political organization like a city, state, or county in the US can specify their time zones. And a few have in our own history.

In addition, the Microsoft OSs do not use the same names for time
zones as UNIX. I see no reason the time zones used by Microsoft
can not also be registered in this registry.

You bring up the point that maybe there will be more than one 'official' authority in addition to Olson.

That time zone database is also not the authority. They do not claim to be official or authoritative . The only official time zones are those defined by the national and regional governments of the word.

In that case I would want to know the source of the data in the registry.

If I use the FOO time zone, it does not matter who defined it. It matters that everyone can tell in a standard way when the meetings will take place. Authority is irrelevant. Consistency between vendors is relevant in iCal.
