The role of time in modern physics requires a robust generalization, free from the constraints placed during the infancy of quantum mechanics and general relativity. I present a more general approach to time in quantum mechanics, in which the core mathematical framework stems from canonical quantum gravity and quantum field theory. We can apply this approach to cosmology and quantum information where the role of time either seemingly fades away or couples with other degrees of freedom. Previous attempts at rectifying the problem of time either ignored the instances where, what they defined as time, failed at providing unitary evolution or focused only on regions away from these so-called turning points. I incorporate these turning points into the methodology to show that not only do we recover unitary evolution but obtain deviations from expected classical evolution. These deviations range from several orders of magnitude above the Plank scale and thus could be experimentally verified.
