N2 - The credibility of orbital period analyses of eclipsing binaries strictly depends on the correctness of the observed mid-eclipse time determination, as well as the reliability of its uncertainty estimation. The majority of them have been determined by means of the Kwee-van Woerden method (KWM). There are also other possibilities - e.g. to use physical models of eclipsing binaries or light curve templates and to determine mid-eclipse times using the least square method (LSM). We compared results yielded by both methods by means of a computer simulation on the synthetic model of the AR Aur primary minimum. Minima times determined by the KWM and the exact LSM approach are nearly the same, while the scatter of LSM times is always smaller than the scatter of KWM times. KWM uncertainties are systematically underestimated. We think that the time is ripe for the Kwee-van Woerden method to retire.
