Contrary to the conviction expressed by J. Kijowski [Phys. Rev. A 59, 897 (1999)] and shared in some other papers, the reasons to look for the 'time operator' in the context of the standard quantum doctrine of orthogonal projectors and self-adjoint observables are highly questionable. Some improved solutions in terms of POV measures invite critical discussions as well.

    Arrival-time statistics in spacelike-separated EPRB measurements depend on their order relative to the preferred foliation, offering a detectable signature and implying superluminal signaling.
