The relevance of observations in introducing time dependence into quantum cosmology is discussed, some of the important features being illustrated by a simple example. Although the concept of time arises in a natural way even with a constant wave function, there are some conceptual difficulties in understanding how arguments which are familiar in classical cosmology translate to the quantum case.
