Created attachment 326430 [details] Replication demo System: Fedora 10 In Gnome 2.24, the clock applet is not able to authenticate the user using the PolicyKit window. There is no way to change the system data. This is an issue inherited from Fedora 9, not yet fixed.
I resolved the issue, modifying the PolicyKit rules: "ALT+F2"/"polkit-gnome-authorization" "org.gnome.clockapplet.mechanism.settime" "Edit"/"Active Console" I modified the value from the default wrong "Authentication" value to "Admin Authentication" value. The same is valid for "org.gnome.clockapplet.mechanism.*". A default consistent-working configuration of PolicyKit for the Clock-Applet maybe appreciated, especially by beginner users. p.s.: Obviously this policy grant the right to modify the date and the time only to the Admin user and not to every one. I think this is a behaviour closer to the Fedora general policy: gpk-update-viewer system-config-services and many others. Every tool requires the admin password to modify a system general parameter, except the clock applet. This brakes in system consistence (IMHO).
