LocalDate减去a Period(如"28年,1个月和27天"),得到错误的结果.

public static void main(String[] args) {
    printAgeAndBirthday(1989, 2, 22);

    printBirthdayFromPeriod(28, 1, 27);
}

    final Period period = Period.of(years, months, days);
    final LocalDate now = LocalDate.now();
    final LocalDate birthday = now.minus(28, ChronoUnit.YEARS)
            .minus(1, ChronoUnit.MONTHS)
            .minus(27, ChronoUnit.DAYS);

    System.out.println("your birthday is : "+ birthday);//1989-02-19
    System.out.println("your birthday is : "+ now.minusYears(28).minusMonths(1).minusDays(27));//1989-02-19
    System.out.println("your birthday is : "+ now.minus(period));//1989-02-19
    System.out.println("your birthday is : "+period.subtractFrom(now));//1989-02-19
    System.out.println("your birthday is : "+ …
