Why time isn't an operator in quantum mechanics?
Associated with each measurable parameter in a physical system is a quantum mechanical operator. Now although not explicitly a time operator the Hamiltonian operator generates the time evolution of the wavefunction in the form H*(Psi)=i*hbar(d/dt)*(Psi), where Psi is a function of both space and time. Also I don't believe that in the formulation of quantum mechanics (QM) time appears as a parameter, not as a dynamical variable. Also, if time were an operator what would be the eigenvalues and eigenvectors of such an operator? Note:A dynamical time operator has been proposed in relativistic quantum mechanics. A paper I found on the topic is; Zhi-Yong Wang and Cai-Dong Xiong , "Relativistic free-motion time-of-arrival", J. Phys. A: Math. Theor. 40 1987 - 1905(2007)
