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. In a canonical formulation coordinate time t absconds from its classical role and instead serves as a gauge parameter. Other phase space variables may generate gauge-independent evolution in a relational sense. In this manner, evolution depends on the differences between different phase space variables. However, relational time still requires a reference variable, preferably one with a monotonic relationship with gauge variable t. Finding an appropriate reference variable and constructing global evolution encompasses the main issue with the problem of time. Possible candidates for this variable, if at all available, couple to other degrees of freedom or exist only locally. In extending from local to global evolution, past solutions encountered instances where the reference variable generated non-unitary evolution at phase space locations defined as turning points. Previous literature in the problem of time either focused on regions away from the turning points or did not address the non-unitary evolution past the turning point. 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.
