Apparently there's new styling for the list elements in the new navigation. All list elements in the .WikiHeaderRestyle > nav block have now bottom border. That includes your timer. Either move the timer somewhere else or remove that bottom through your CSS style sheets or the functions that added the timer in the first place.
