摘要：

''Time'' as an observable of a physical system is to be understood with reference to the evolution of some nonstationary quantity. Thus, any observable 'time'' is the time of occurrence of an event of a certain type, defined by the appearance of some specified value of the dynamical quantity in question. This interpretation of time observables is illustrated by means of some examples.
