--- Comment #22 from Jonathan Wakely <redi at gcc dot gnu.org> --- I do still consider it incorrect. But what I mean re libc++ is that *even ignoring* the general problems with using TZ, *their implementation* of using TZ isn't even correct. If the intention is to follow POSIX, it fails to do that.
