Dear Maintainer,
One of qcustomplot autopkgtests fails when run against Qt 5.14, currently
available in experimental. It fails because of stderr:
[ 83%] Building CXX object CMakeFiles/plots.dir/mainwindow.cpp.o
/tmp/tmp.vk2CMqIqRc/src/mainwindow.cpp: In member function ‘void
MainWindow::realtimeDataSlot()’:

Attached is a patch that changes the code to use QElapsedTimer, as suggested.
It works with Qt 5.12 too.
