    Description

      Consider the following test snippet:

          QElapsedTimer timer;
    timer.start();
    QTest::qWait(100);
    QCOMPARE(timer.elapsed(), 100);

      When executing this test one gets:

      FAIL!  : [snip] Compared values are not the same
   Actual   (timer.elapsed()): 99
   Expected (100)            : 100

      This broke some auto tests we used in KDE and which used to pass when compiling against Qt 5.7. See for example: https://build.kde.org/view/Plasma/job/Plasma%20kdecoration%20kf5-qt5%20SUSEQt5.9/4/
