Unable to set start or stop time.

I’m unable to set a start or stop time for the plugin. I can select a time and date, but upon hitting “Update Settings” any changes to that field are wiped out.

Debug Helpers:
You can append &debug after the wp-topbar URL to turn on debugging messages. i.e. admin.php?page=wp-topbar.php&debug . These messages can help you see if you have a parameter that will cause the TopBar to break.
&debug will turn on an internal timer that will display debug messages for about one minute. The timer is reset for every page refresh that has &debug. If you have debugging turned on (in your wp-config.php), then the error messages will also be sent to the default WordPress logfile for any non-admin page views of your website. i.e. define(‘WP_DEBUG’, true); and define(‘WP_DEBUG_LOG’, true);
To turn off the debug messages, remove the &debug from the URL and wait about one minute.
