Most of the time, yes.  Are there any weird cases out there, with
overlapping time zones? For example, a country where some religious
minority doesn't observe DST; then which time zone you want will depend on
the user's religion.

Or suppose you're at sea, on a course that takes you in and out of
international waters.  In international waters, there won't be any
authority issuing time zone rules; in national waters, there will be, but
you won't really care; you'll want to keep a consistent clock (particularly
if you're going more or less north-south).  So what time zone you follow
will probably be up to the captain of the ship.  (Extra Bonus
Complication: consider nations such as Libya, which claim sovereignty out
to 100 miles, even though nobody listens.  The borders reported by your
timezone registry may have to be localized depending on what nation the
user is in.)

I suppose those can be handled by returning multiple values, though, and
letting the user pick.  We just need to make sure that nobody builds a
VEVENT which contains a LOCATION but no TZID, and expects the recipient to
look it up by location.
