      the OpcUaViewer Qt example project. In mainwindow.cpp, within the method MainWindow::showHistorizing() (starting at line 447), a QOpcUaHistoryReadRawRequest is created.

      The startTimestamp argument is set to a later date than the endTimestamp (by 2 days), which leads to unpredictable responses from the server.

      void MainWindow::showHistorizing()
{
    ....
    auto request = QOpcUaHistoryReadRawRequest(
                {QOpcUaReadItem(nodeId)},
                QDateTime::currentDateTime(),
                QDateTime::currentDateTime().addDays(-2),
                5,
                false
                ); 
    .....
}
