We explore a cosmological model in which the time scale is variable with theexpansion of the universe and the effective spacetime is driven by the inflatonfield. An example is considered and their predictions are contrasted betweenPlanck 2018 data. We calculate the spectrum indices and the slow-rollingparameters of the effective potential. The results are in very good agreementwith observations.
