Summary:The definition of the quantum corridor describing monitoring a quantum observable in the framework of the phenomenological restricted-path-integrals approach is generalized for the case of finite resolution of time. The resulting evolution of the continuously measured system cannot be presented by a differential equation. Monitoring position of a quantum particle is considered then with the help of a model taking into account finite resolution in measurement of time. The results based on the model are shown to coincide with those of the phenomenological approach.
