(The Time class) Design a class named Time. The class contains:
Data fields hour, minute, and second that represents a time.
A no-arg constructor that creates a Time object for the current time.


A constructor that constructs a Time object with a specified elapse time since midnight, January 1, 1970 in milliseconds. (The data fields value will represent this time.)



굵게 표신한 부분이 뭘 말하는건지 모르겠어

1970 1월 1일부터 시간이 얼마나 지났냐를 말하는건가?

근데 밀리세컨을 받아서 어떻게 세팅하지......

일단 time class 는 calendar 를 사용하긴 했는데
