    I have a date time format like this

    "2020-04-26T11:16:59+01:00"
    

    I tried this code and also different formatst, i always get an invalid QDateTime.

    QString datetime("2020-04-26T11:16:59+01:00");
    QString formatst("yyyy-MM-ddTHH:mm:ss±tzoff");
    //QString formatst("yyyy-MM-ddTHH:mm:ss±HH:mm");
    //QString formatst("yyyy-MM-ddTHH:mm:ssZHH:mm");   
    QDateTime dt;
    dt.fromString(datetime, formatst);
    qDebug() << Q_FUNC_INFO << datetime << dt;
    

    Can someone help to find convert the date/time from string?

      1. That's a Qt::ISODate format, you can use fromString(datetime, Qt::ISODate)
      2. QDateTime::fromString() is a static method, it won't do any change to your dt object.
        So the correct way is
      QDateTime dt = QDateTime::fromString(datetime, Qt::ISODate);
