问题及代码：
    
    
    
    public class Get_the_data {
    	public static void main(String[] args) {
    
    		int year = 1970, month = 1, days, hours, minutes;
    		long Get_second = (long) (System.currentTimeMillis() / 1000);      //取出0区的时间
    
    		// 一般的 年 月 日的时间
    		int Year_sec = 365 * 24 * 60 * 60;
    		int[] Month_day = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
    		int Day_sec = 24 * 60 * 60;
    		int Hour_sec = 60 * 60;
    		int Minute_sec = 60;
    
    		while (Get_second >= Year_sec) // 算出年数
    		{
    			year++;
    			Get_second -= Year_sec;
    			if ((year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)) {
    				Get_second -= Day_sec;
    			}
    		}
    
    		if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) // 确定现在是否是闰年
    			Month_day[2] = 29;
    
    		int i = 1;
    		while (Get_second >= Day_sec * Month_day[i]) // 算出月份
    		{
    			month++;
    			Get_second -= Day_sec * Month_day[i];
    			i++;
    		}
    
    		String Months;
    		switch (month) {
    		case 1:
    			Months = "January";
    			break;
    		case 2:
    			Months = "February";
    			break;
    		case 3:
    			Months = "March";
    			break;
    		case 4:
    			Months = "April";
    			break;
    		case 5:
    			Months = "May";
    			break;
    		case 6:
    			Months = "June";
    			break;
    		case 7:
    			Months = "Jule";
    			break;
    		case 8:
    			Months = "August";
    			break;
    		case 9:
    			Months = "September";
    			break;
    		case 10:
    			Months = "October";
    			break;
    		case 11:
    			Months = "November";
    			break;
    		case 12:
    			Months = "December";
    			break;
    		default:
    			Months = "Error!";
    			break;
    		}
    
    		days = (int) (Get_second / Day_sec + 1); // 确定现在的天
    		Get_second %= Day_sec;
    
    		hours = (int) (Get_second / Hour_sec+8); // 确定现在的小时（北京时间）
    		Get_second %= Hour_sec;
    
    		minutes = (int) (Get_second / Minute_sec); // 确定日期的分钟
    
    		Get_second %= Minute_sec; // 确定日期的秒数
    
    		System.out.print("Current date and time is " + Months + " " + days
    				+ ", " + year + "   " + hours + ":" + minutes + ":"
    				+ Get_second);
    	}
    }
    
    
    
    运行结果：
