    time.setFullYear(time.getFullYear() - 70);
    const year = time.getFullYear();
    const month = time.getMonth() + 1;
    const date = time.getDate() - 1;
    const format = '-';
    return (
      year + format + (month < 10 ? `0${month}` : month) + format + (date < 10 ? `0${date}` : date)
    );
