  We propose a procedure to obtain exact analytical solutions to the
time-dependent Schr\"{o}dinger equations involving explicit time-dependent
Hermitian Hamitonians from solutions to time-independent non-Hermitian
Hamiltonian systems and the time-dependent Dyson relation together with the
time-dependent quasi-Hermiticity relation. We illustrate the working of this
method for a simple Hermitian Rabi-type model by relating it to a non-Hermitian
time-independent system corresponding to the one-site lattice Yang-Lee model.
