++ *    Fedora/Mandriva: the ZONE key in /etc/sysconfig/clock
++ *    openSUSE: the TIMEZONE key in /etc/sysconfig/clock
++ *    Solaris/OpenSolaris: the TZ key in /etc/TIMEZONE
++ *    Arch Linux: the TIMEZONE key in /etc/rc.conf
++ *    Gentoo (old): the ZONE key in /etc/conf.d/clock
++ *
++ *    FIXME: reading the system-tools-backends, it seems there's this too:
++ *           Solaris: the TZ key in /etc/default/init
++ *                    /etc/TIMEZONE seems to be a link to /etc/default/init
