The description of quantum evolution using unitary operator requires that the underlying self-adjoint quantum Hamiltonian remains time-independent. In a way extending the so called -symmetric quantum mechanics to the models with manifestly time-dependent "charge" we propose and describe an extension of such an exponential-operator approach to evolution to the manifestly time-dependent self-adjoint quantum Hamiltonians .
