Date/Calendar/System三者的时间各不相同，求解释

[Sodino]

		arg = "201011011028";//当手机时间显示为2010年11月1日10点28分时
		int year = Integer.parseInt(arg.substring(0, 4));
		int month = Integer.parseInt(arg.substring(4, 6));
		int day = Integer.parseInt(arg.substring(6, 8));
		int hour = Integer.parseInt(arg.substring(8, 10));
		int minute = Integer.parseInt(arg.substring(10, 12));
		Date date = new Date(year, month, day, hour, minute);
		//此处输出：61249314480000
		Log.d("AndroidLabInfo", String.valueOf(date.getTime()));

		Calendar calendar = Calendar.getInstance();
		calendar.set(year, month, day, day, minute);
		//此处输出：1291138110095
		Log.d("AndroidLabInfo", String.valueOf(calendar.getTimeInMillis()));
		//此处输出：1288578570096
		Log.d("AndroidLabInfo", String.valueOf(System.currentTimeMillis()));

三个数各不相同，请问这是为什么呢？

谢谢....

其实大部分错误的情况是：月份是0-11，而不是1-12这样

[Sodino]

calendar.set(year, month, day, day, minute);
应改为
calendar.set(year, month, day, hour, minute);

写错了，呵呵，但

1291138110095与1288578570096的差距仍然是太大了啊

Date侧重日期，是jdk1.0就有的
Calendar是jdk1.1增加的，侧重日历时间，便于国际化时间，是系统推荐使用的。


JAVA的Date类与Calendar类比较
