// The TimeStamp class represents time with integers for the day,
// hour, min, and second.  We can increment a TimeStamp by adding an
// integer number of seconds.  We can compute the difference or time
// elapsed between two TimeStamp objects. Timestamp objects can be
// sorted chronologically.  TimeStamp objects are printed in military
// format (00:00:00 -> 23:59:59).
