The timestamps are currently updated by the settings service that
provides the connection.  nm-applet updates the timestamp of any of it's
active connections on a 5-minute timer.  System connections currently
don't update their timestamps because not all plugins support timestamps
yet, though we should really make it work for those plugins that do.

Since you mention 'connections.cfg' that indicates you're not using
nm-applet, which  means that whatever GUI client you are using would
need to do the connection updating.
