public class my_first {
public static void main(String[] args) {
Calendar my_cal_d1 = Calendar.getInstance();// created calendar 
System.out.println( my_cal_d1.getTime());
System.out.println( my_cal_d1.getTimeInMillis());
long my_time2=my_cal_d1.getTimeInMillis();
my_cal_d1.setTimeInMillis(my_time2);
System.out.println( my_cal_d1.getTime());
}
}
