We analyze the issue of dynamical evolution and time in quantum cosmology. emphasize problem choice phase space variables that can play role a parameter such way for expectation values operators classical is reproduced. show it neither necessary nor sufficient Poisson bracket between variable super-Hamiltonian to be equal unity all space. also discuss question switching different internal times as well Montevideo interpretation theory.
