    GSettings Bindings rely on quarks
    
    There is a fake change notify on timezone when either a corresponding
    file changes or the setting for "use system timezone" changes,
    to propagate the change in the code properly. This notify requires
    proper key identification for GSettings bindings, because without it
    the binding crashes on a runtime check.
