While I personally have no use for such a plugin, I have some thoughts
on how it might be implemented. Take all this with a grain of salt as
it's late and I should be asleep instead of trying to think. :-)

The timezone to display would be determined by this priority order:

1. The timezone returned by their copy of the plugin (if this is
implemented). See plugins like gaim-encryption for ways to sneak extra
data through IM messages.

2. The timezone set manually.

3. The timezone obtained via their IP address (using that GeoIP database
or whatever it's called). (Obviously, this is only useful when their IP
address can be obtained.)

4. The timezone obtained by parsing something like their city in their
profile (however that's stored per-protocol).

Gaim has functions that plugins can use to store a preference on a blist
node. You'd just use one of these and store it as an integer (as a Unix
time value). You'd probably cache a timezone value and use that in the
future if you couldn't obtain a new timezone. Some sort of indication
would be provided (be it a different color or italics or whatever) to
show that you were using a cached value instead of a recently updated
one. You might also show that indicator (or another one) for timezones
that were obtained via parsing static data like their profile. Perhaps
you'd have some color coding of how reliable it was (green for the first
on down to red for a cached copy).
