第六章第三十三题（当前日期和时间）(Current date and time)_希望变量current_da的值

**6.33（当前日期和时间）调用System.currentTimeMillis()返回从1970年1月1日0点开始至今为止的毫秒数。编写程序，显示当前日期和时间。

下面是运行示例：
Current date and time is May 16, 2012 10:34:23

**6.33(Current date and time) Invoking System.currentTimeMillis() returns the elapsed time in milliseconds since midnight of January 1, 1970. Write a program that displays the date and time.

Here is a sample run:
Current date and time is May 16, 2012 10:34:23

下面是参考答案代码:

public class CurrentDateAndTimeQuestion33 {
   
	public static void main(String[] args) {
   
		// Obtain the total milliseconds since midnight, Jan 1, 1970
		long totalMilliseconds = System.currentTimeMillis();

		// Obtain the total seconds since midnight, Jan 1, 1970
		int totalDays = (int) (totalMilliseconds / 1000 / 60 / 60 / 24);

		long totalSeconds = totalMilliseconds / 1000;

		// Compute the current second in the minute in the hour
		long currentSecond = totalSeconds % 60;
		// Obtain the total minutes
		long totalMinutes = totalSeconds / 60;

		// Compute the current minute in the hour
		long currentMinute
