Week five Project 4-static member application

Design a time class that contains static data members and member functions. A static data member is a common data for all objects in a class, in the following design, whether the clock is to be 12-hour or 24-hour, or if the number that is less than two digits is preceded by 0, is a "global" setting that is appropriate as a static data member in the class.
