wycks on "[Plugin: Disable WordPress Core Updates] PHP Notices"

As Robert Chapin said the problem is that it will ping for updates on every load when these filters are set (so it seems).

I have used this to remove it it from pinging for updates and the nag screen,

function remove_core_updates(){

        global $wp_version;
        return (object) array(
            'last_checked' => time(),
            'version_checked' => $wp_version,
            );
}
add_filter('pre_site_transient_update_core', 'remove_core_updates');
add_filter('pre_site_transient_update_plugins', 'remove_core_updates');
add_filter('pre_site_transient_update_themes', 'remove_core_updates');

It still throws a PHP warning "“Trying to get property of non-object", no idea how to fix that without changing core, also there seems to be no way to hook into dismissed_updates.
