Independent timezone name repository
Main use-case is better presentation of timezones to users and support for timezone selection done by users.
CLDR describes other variants of timezone names like BCP47-identifiers ("uslax" for "America/Los_Angeles" etc.), regional formats ("Los Angeles Time" or "Italy Time") and the extra pattern symbol "V" (count 1 => BCP47 id, count 2 => tzid (IANA format, actually supported by Time4J), count 3 => exemplar city and count 4 => regional format). All the underlying data are missing in Java and Android.
A better support is possible based on an extra tz name repository which could be integrated into the olson-module. Without this, the fallbacks described in CLDR could be used and might even apply for Java 6+7 and Android, see also:
Hello, Thanks for this great project. Using Time4A, is it possible to get timezone providing location coordinates?
