BST0BDT should be GMT0BST JST-9JDT should be JST-9 (no daylight savings in Japan). I think there may also be no daylight savings in India, but I'm not sure. Also, I think enabling the zoneinfo style names only on GNU/Linux and MS DOS is too conservative. All BSD based systems use the zoneinfo database, as do most SYSV ones AFAIK. It may be better to use those by default, and enable the legacy ones on a case by case basis, particularly since there may be problems with the legacy posix ones' handling of DST on many platforms other than Windows (which we know always uses US switchover dates).
