    • Type: Bug

    • Priority: Not Evaluated
    • Resolution: Invalid
    • Affects Version/s: 5.15.2
    • Fix Version/s: None
    • Component/s: Core: Date/Time

      macOS, Windows

      Description

      on macOS, this correct date is reported as QDateTime(Invalid)

      qDebug() << QDateTime(QDate(1976, 3, 28), QTime(1, 0, 0), QTimeZone("Europe/Paris"));

      on Windows, this one is also reported as QDateTime(Invalid)

      qDebug() << QDateTime(QDate(1976, 3, 28), QTime(2, 0, 0), QTimeZone("Europe/Paris"));

      it seems that the problem only occurs with this particular date, 1976-03-28

      it's an important issue because
      QDatetime(anydatebefore1976_03_28).msecsTo(anydateafter1976_03_28)
      is wrong

      thanks for your wonderful work !
