Quantum field theories dictate that spacetime be structured in discrete terms. This paper proposes an alternate structure for the definition of time, and describes experimental approaches that will validate the hypothesis. Also proposed in this paper is the existence of an Absolute Frequency that pervades the entire physical universe. This fundamental frequency may be within the detectable range of current instruments and technology, and can be utilized as a new reference standard for all measurement systems. Each reader must comprehend that our universe literally blinks, off and on, more than 1 trillion times each second.
