Now that I think of it, maybe they don't intend to support right timezones at all, if they are so scrupulous about POSIX: TAI-10 is not POSIX. As if POSIX deserved such respect...
musl supports the zoneinfo format, according to http://www.etalabs.net/compare_libcs.html So as long as it does, there's no reason why it shouldn't support the right/ timezones, which are zoneinfo timezones just like POSIX ones. It's just that TAI-10 isn't a widely used setup, so the zoneinfo parsing code probably hasn't been extensively tested in musl with right/ zones yet. -- Laurent
