    "abstract": "The problem of time operator in quantum mechanics is revisited. The unsharp\nmeasurement model for quantum time based on the dynamical system-clock\ninteraction, is studied. Our analysis shows that the problem of the quantum\ntime operator with continuous spectrum cannot be separated from the measurement\nproblem for quantum time.",
