如何获取当前时间到晚上12点的毫秒差值

		Calendar calendar = Calendar.getInstance();
        calendar.add(Calendar.DAY_OF_YEAR,1);
        calendar.set(Calendar.HOUR_OF_DAY,0);
        calendar.set(Calendar.SECOND,0);
        calendar.set(Calendar.MINUTE,0);
        calendar.set(Calendar.MILLISECOND,0);
        Long timeOut = (calendar.getTimeInMillis()-System.currentTimeMillis()) / 1000; //晚上十二点与当前时间的毫秒差
        System.out.println(timeOut);
