Turing Machines have no real time clock and no interrupt. If we assume the comp hypothesis (purely based on Turing machines) and the anthropic principle, then the flow of consciousness can only be constrained by the logical nature of the links pernitting transitions from one observer moment to the next. Time therefore is an illusion derived from such a logical flow.
Having said that, I am puzzled by the fundamental quantization of the world and the constancy of Planck's constant everywhere and at all time. To achieve such a universal "clock" we could assume: 1) either that at the heart of the comp hypothesis there exist a large number of Turing machines all requiring a real time clock responsible for this quantization. This implies a weakening of comp and the assumption that time is real. I do not favor this explanation. 2) or that all events in our universe share the same (identical) mechanism for transition from observer moment to the next. In other words we all realized (or simulated) by the same Turing machine (or otherwise equivalent CPU). All physical time intervals are defined according to the cycle time/interval of this single machine which is generating not just our universe, but our Multiverse (all the universes accessible through QM. ) This cycle time corresponds to Planck constant which is absolute in the sense that it defines our own frame of reference. So, (relatively speaking,) from our point of view it appears to be absolute. From the point of view of an observer outside our Multiverse, its actual value could be very small or very large. BTW, the existence of the same types of particles (electrons, photons...) across the Multiverse indicate the existence of a common implementation that goes beyond just a common Turing machine cycle time. In other words, some of the basic software across the Multiverse is also identical. i.e., the basic driver software Version 1.0 for electrons is identical across the Multiverse. This lead to the possibility that the QM Multiverse < the Plenitude George Levy
