[gdm/wip/initial-setup2: 19/20] Port gdm-initial-setup to timedated

[Matthias Clasen <matthiasc src gnome org>]

commit 44511bde0cf70d1c2e274ff9fb63b1766b2c9794
Author: Matthias Clasen <mclasen redhat com>
Date:   Fri Apr 6 10:28:41 2012 -0400

    Port gdm-initial-setup to timedated
    
    gnome-settings-daemon does not ship its own datetime mechanism
    anymore, so we have to do the same thing as gnome-control-center,
    and use the systemd mechanism.
