整数(秒数)转换为时分秒格式(xx:xx:xx)

// a integer to xx:xx:xx
    public static String secToTime(int time) {
        String timeStr = null;
        int hour = 0;
        int minute = 0;

        else {
            minute = time / 60;
            if (minute < 60) {
                second = time % 60;
                timeStr = unitFormat(minute) + ":" + unitFormat(second);
            } else {
                hour = minute / 60;
                if (hour > 99)

                minute = minute % 60;
                second = time - hour * 3600 - minute * 60;
