Abstract (EN): Difficulties in the interpretation of the wave function of the Universe in canonical quantum gravity suggest that the use of dynamical variables to play the role of time is not quite consistent. A formulation of canonical quantum gravity in which time is an extrinsic variable has been previously studied with the problem of being compatible, at the classical level, with General Relativity with a nonvanishing unspecified cosmological constant. We argue that this last problem can be circumvented by introducing a nondynamical scalar field which allows for a relaxation mechanism for the cosmological term.
