Hi @Khalifa,

How can I Calculate the time span between two times

If you mean between two QDateTimes, you can use QDateTime::daysTo, QDateTime::secsTo, or QDateTime::msecsTo, like:

QDateTime then = QDateTime::currentDateTime();
QThread::msleep(100);
QDateTime now = QDateTime::currentDateTime();
qDebug() << then.msecsTo(now);

Or if you mean between to points in time, you can use QElapsedTimer, like:

QElapsedTimer timer;
timer.start();
QThread::msleep(100);
qDebug() << timer.elapsed();

Cheers.

Someone started working on a QTimeSpan class long ago, but it hasn't made it into the official code base yet: https://forum.qt.io/topic/3160/qtimespan-interest

I have a pretty complete timespan implementation here:

There's a bunch of other goodies in this library as well. Here's a link to the whole enchilada:
