Abstract
The problem of time operator in quantummechanics is revisited. The unsharp measurement modelfor quantum time based on the dynamical system-clockinteraction is studied. Our analysis shows that theproblem of the quantum time operator with continuousspectrum cannot be separated from the measurementproblem for quantum time.
