   Not reliable - to work, that means that the machine must be re-booted exactly   
   once every day, no more and no less; and that one considers the possibility of   
   post-midnight use.   
      
   Remember that rebooting may be forced by power failure, Windows updates   
   software failures, engineers, etc.; and watch out for the International Date   
   Line.   
      
   An improvement, perhaps a generally sufficient one, would be to alter   
   Yesterday only if the value of Today changes.
