/*******************************************************************************
// MODULE NAME: TimeType
// INTERFACE FILE:      baltime.h
// IMPLEMENTATION FILE: baltime.cpp
//
// PURPOSE: To create a TimeType useful in an implementation of the BAL program,
// allowing the user to create a new object, change its value, determine if it
// contains an invalid or default value, and print the current or default value
//
// FUNCTIONS:    Name             Purpose
//              TimeType        Parameterless Constructor
//              isValid         Tests whether the time is valid
//              isDefault       Tests whether the time is a default value
//              Equals          Show whether this time === another
//              LessThan        Show whether this time < another
//              GreaterThan     Show whether this time > another
//              Print           Print the current value of the object
//              Default         Print the default value of the object
//              valueIs         Print the current value of the object
//              Limits          Show the limits on the object
//              Store           Set the time as indicated by 2 ints
//              Store           Set the time as indicated by a string
//              Reset           Change the time to its default value
