QDate - wrong year

I have the following situation:

   QDate fixDate = QDate::fromString(QString("270912"), "ddMMyy");

the year returned is 1912. I do not understand why and how get the correct year.

Thanks in advance

Solution

  • Qt always interprets a two-digit year as 19yy. So it's best to modify the input string to look like YYYY.

    Note: parsing it as YY and adding 100 years fails on Feb 29, 2000. '22900' is seen as February 29, 1900, but - surprise! - in the Gregorian calendar 1900 is not a leap year. So you get an invalid QDate, which remains invalid after adding 100 years to it.
