POSIX states that the use of ':' introduces implementation-defined extensions. http://www.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html > The value of TZ has one of the two forms (spaces inserted for clarity): > > :characters > > or: > > std offset dst offset, rule > > If TZ is of the first format (that is, if the first character is a <colon>), > the characters following the <colon> are handled in an implementation-defined > manner. > In other words, since "Europe/Paris" is NOT a valid timezone according to POSIX rules, a user concerned about POSIX compliance should be allowed to use TZ=":Europe/Paris" to still get glibc semantics of a named zone. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
