    Description

      Test 'tst_QTimer::remainingTime() ' has failed 23 times within the last week in the CI. It's a flaky test and doesn't necessarily fail the whole integration.

      FAIL!  : tst_QTimer::remainingTime() 'qAbs(remainingTime - 150) < 50' returned FALSE. (91)
tst_qtimer.cpp(167) : failure location

      Could those fails be related to high CPU load on the CI machines?

      Or are they related to "Improve QTest::qWait() precision and switch to QDeadlineTimer" 374a173d1417a9f8c313088420cb1b792fe45977 (qtbase) https://codereview.qt-project.org/#/c/182747/ ?
