   In classical mechanics, if there's an explicit time dependence in the Hamiltonian of a system, then it won't be equal to the system's total energy. Why isn't this true in quantum mechanics?

   Can you show an example of this?
   
   If the time-dependence in the Hamiltonian is just some external potential, it should be fine. And I do not see how you get different time-dependent expressions in quantum mechanics - the particles and fundamental interactions have to stay the same.

   No, I can't. I just confused myself. Thanks.
