Chapter 17, Problem 17.22E

(Time Class Modification) It would be perfectly reasonable for the Time class of Figs17.4–17.5 to represent the time internally as the number of seconds since midnight rather than the three integer values hour, minute and second. Clients could use the same public methods and get the same results. Modify the Time class of Fig17.4. to implement the time as the number of seconds since midnight and show that there is no visible change in functionality to the clients of the class. [Note: This exercise nicely demonstrates the virtues of implementation hiding.]
