    Description

      When system locale short date is set to show the year with two digits only the QDate::fromString() conversion results in a wrong century (1900 instead of 2000).

      // System local short date: dd-MMM-yy
QDate d1= QDate::currentDate();
QString s1 = d1.toString(Qt::SystemLocaleShortDate); // "11-Mrz-19"
QDate d2= QDate::fromString(s1, Qt::SystemLocaleShortDate);
QString s2 = d2.toString("dd.MM.yyyy"); // "11.03.1919"

      In 2019 the base century should be 2000 for two digit year dates.
