java之時，分，秒的計算方法

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");
		for (MyUpcomingVo myUpcomingVo : myUpcomingVoList) {
			long nd = 1000 * 24 * 60 * 60;
			long nh = 1000 * 60 * 60;
			long nm = 1000 * 60;
			Date nowDate;
			try {
				nowDate = df.parse(df.format(new Date()));
				System.out.println(nowDate.getTime() - df.parse(myUpcomingVo.getProcessNodeExamineTime()).getTime());
				// 獲得兩個時間的毫秒時間差異
				long diff = (nowDate.getTime() - df.parse(myUpcomingVo.getProcessNodeExamineTime()).getTime());
				// 計算差多少天
				long day = diff / nd;
				// 計算差多少小時
				long hour = diff % nd / nh;
				// 計算差多少分鍾
				long min = diff % nd % nh / nm;
				myUpcomingVo.setDeadline("已耗時" + day + "天" + hour + "小時" + min + "分鍾");
			} catch (Exception e) {
				throw new RuntimeException(e.getMessage());
			}
