The Overtime Interpretation of Quantum Mechanics

A key conceptual achievement of special relativity was the replacement of absolute time with an operational notion of simultaneity defined through clock synchronization. Extending this logic to quantum theory, we propose the Overtime interpretation, in which quantum systems evolve in an internal time $\tau$ that becomes related to the observer's time $t$ only through physical synchronization with macroscopic apparatus. Measurement is thus understood as temporal embedding rather than physical collapse. This framework introduces no new ontological entities or modifications to quantum formalism, but clarifies when temporal statements about quantum systems are physically meaningful. We formalize this idea through a synchronization map acting on the composite system–apparatus structure. The approach preserves all standard predictions, maintains compatibility with relativity, and provides a unified resolution of canonical quantum paradoxes—including Schrödinger's cat, Wigner's friend, the Frauchiger--Renner theorem, Bell-type experiments, and delayed-choice phenomena—by identifying a common source: the illegitimate combination of temporal statements across unsynchronized frameworks.
