Qt QLCDNumber QTimer Digital Clock

I am trying to create a digital clock. However, my purpose is not getting the currentTime(). Instead, I am defining my own time and incrementing the time from there onwards.

However, in my codes, I am able to call tickSimulation(), but the clock timer won't start ticking. It just stuck at 11:00:00. Is adding addMSecs(1000) the correct way to increment the time?

Please help. Thanks!

Code:

---

StatusBar::StatusBar()
{
    createButtons();
    time = new QTime(11, 0, 0);
};
 
void StatusBar::createButtons()
{
    ...
    lcdSimulation = new QLCDNumber;
    lcdSimulation->setNumDigits(8);
    simulationTimer = new QTimer;
    simulationTimer->start(1000);
    QObject::connect(simulationTimer, SIGNAL(timeout()), this, SLOT(tickSimulation()));
    addWidget(lcdSimulation);
    ...
}
 
void StatusBar::tickSimulation()
{
    QString text = time->toString(Qt::TextDate);
    lcdSimulation->display(text);
    time->addMSecs(1000);
};

Line 23 should be :

Code:

---

time = time->addMSecs(1000);

Carefully read the description of the method QTime::addMSecs
