Abstract
The notion of “Probabilistic Time” is studied as a way to obtain Quantum Field Theory in curved space-time from Quantum Gravity. It is shown how ideal and real clocks measure the probabilistic time and how the universe can be used a a real clock. The problem of the arrow of time is studied because it is related with the definition of probabilistic time.
