    "abstract": "Possible theoretical frameworks for measurement of (arrival) time in the\nnonrelativistic quantum mechanics are reviewed. It is argued that the ambiguity\nbetween indirect measurements by a suitably introduced time operator and direct\nmeasurements by a physical clock particle has a counterpart in the\ncorresponding classical framework of measurement of the Newtonian time based on\nthe Hamiltonian mechanics.",
