1. Represent a point in time by using an int to store the number of seconds since January 1,1970. When will programs that use this representation face a time bomb? How should you proceed when that happens?

2. Time. Develop a data type for the time of day. Provide client methods that return the current hour, minute, and second, as well as to String() and compare To() methods. Develop two implementations: one that keeps the time as a single int value (number of seconds since midnight) and another that keeps three int values, one each for seconds, minutes, and hours.
