  In canonical quantum cosmology, the wave function of the universe lacks
explicit time dependence. However, time evolution may be present implicitly
through the semiclassical superspace variables, which themselves depend on time
in classical dynamics. In this paper, we apply this approach to an oscillating
universe model recently introduced by Graham et al. By extending the model to
include a massless, minimally coupled scalar field $\phi$ which has little
effect on the dynamics but can play the role of a "clock", we determine the
decay rate of the oscillating universe.
