     * For example:
     * # /etc/locale.conf
     * LANG=pt_PT.UTF-8
     * LC_TIME=pt_PT.UTF-8
     *
     * # ~/.config/plasma-localerc

     * The end result is LANG=en_US.UTF-8, LC_TIME=pt_PT.UTF-8
     * But we will display LC_TIME as "en_US.UTF-8 inherit from LANG",
     * because it is NOT SET BY US.
     *
     * Explicit set LC_TIME in ~/.config/plasma-localerc in this case
     * should fix the issue.
