Abstract
A definition for the intrinsic time co-ordinate is proposed, using the phase of the wave function of the universe. The definition generalizes the notion of time co-ordinate which arises in the semiclassical cosmology. It also leads to acceptable results for the evaluation of expectation values of physical variables.
