java 将毫秒转换为 *天*时*分*秒 的格式

    public static String formatDuring(long mss) {
        long days = mss / (1000 * 60 * 60 * 24);
        long hours = (mss % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60);
        long minutes = (mss % (1000 * 60 * 60)) / (1000 * 60);
        long seconds = (mss % (1000 * 60)) / 1000;
        return days + " 天 " + hours + " 小时 " + minutes + " 分钟 "
                + seconds + " 秒 ";
    }
