Comment on: "On the standard quantum-mechanical approach to times of arrival"

The status of the arrival time distributions of Allcock and Kijowski and their generalizations, which are all obtained using conventional quantum mechanics, is discussed in the light of some "paradoxes" pointed out by Leavens and some other recent results on a fluorescence based operational time-of-arrival model. We claim that the paradoxical aspects dissolve away from the point of view of the standard interpretation of quantum mechanics. Nevertheless, the relation with actual measurement devices is problematic and the limitations for implementing such a connection are made explicit.
