算两个时间差(精确到毫秒)

     
Java中计算两个时间差(精确到毫秒)
 SimpleDateFormat dfs = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        long between = 0;
        try {
            java.util.Date begin = dfs.parse("2009-07-10 10:22:21.214");
            java.util.Date end = dfs.parse("2009-07-20 11:24:49.145");
            between = (end.getTime() - begin.getTime());// 得到两者的毫秒数
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        long day = between / (24 * 60 * 60 * 1000);
        long hour = (between / (60 * 60 * 1000) - day * 24);
        long min = ((between / (60 * 1000)) - day * 24 * 60 - hour * 60);
        long s = (between / 1000 - day * 24 * 60 * 60 - hour * 60 * 60 - min * 60);
        long ms = (between - day * 24 * 60 * 60 * 1000 - hour * 60 * 60 * 1000
                - min * 60 * 1000 - s * 1000);
        System.out.println(day + "天" + hour + "小时" + min + "分" + s + "秒" + ms
                + "毫秒");

android 計算時間相差
Date dateStart = format.parse(info.stratTime);
Date dateEnd = format.parse(info.endTime);
//date.getTime()所返回的是一个long型的毫秒数
Long time = (Long) ((dateEnd.getTime() - dateStart.getTime())/1000);
int second = (int) (time % 60); 
int minute = (int) (time / 60 % 60);
int hour = (int) (time / 60 / 60);
texts[0] += "  " + hour + "時" + minute + "分" + second + "秒";
