Try uninstalling all of the updates first, after they are uninstalled, do a soft reset.

Now download and reinstall the MS update, soft reset after install. Switch yourself to a "Visiting" time zone, click OK, then soft reset. Go back to the clock applet, change yourself back to your time zone (Central) in the "Home" time zone. Soft reset.

See if that works, if not try changing to Eastern, and then soft resetting and change back to Central.
