If you compare QElapsedTimer::elapsed() with QElapsedTimer::nsecsElapsed(), you will find QElapsedTimer::elapsed() to be inaccurate by up to 1 millisecond:
$ ./elapsedtest Wait for 53 ms QElapsedTimer::elapsed(): 53 QElapsedTimer::nsecsElapsed(): 53096276 $ ./elapsedtest Wait for 53 ms QElapsedTimer::elapsed(): 54 QElapsedTimer::nsecsElapsed(): 53093277 $ ./elapsedtest Wait for 53 ms QElapsedTimer::elapsed(): 53 QElapsedTimer::nsecsElapsed(): 53094545 $ ./elapsedtest Wait for 53 ms QElapsedTimer::elapsed(): 54 QElapsedTimer::nsecsElapsed(): 53089063
