Comment 3 for bug 67803

Here an strace attach
$ strace -o time-admin.strace time-asmin
in which the only error I see (my be an normal condition) is an resource unavailable reading /'var/run/dbus/system_bus_socket'

$? == 255

time-admin.strace lines 1426-1446/5790 byte 103094/403277 25%

$ gksudo time-admin
works but display warning messages

(time-admin:16141): GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed.

---------

/usr/share/menu/gnome-system-tools does not has gksudo

?package(gnome-system-tools):needs="X11" section="Apps/System"\
  hints="Time"\
  title="Time Admin" command="/usr/bin/time-admin"\
  icon="/usr/share/gnome-system-tools/pixmaps/time.xpm"

packages which works like firestarter does has gksudo
$ cat firestarter
?package(firestarter):needs="X11" section="Apps/Net" \
 title="Firestarter" command="gksudo /usr/sbin/firestarter" \
 icon="/usr/share/pixmaps/firestarter.xpm"
