    A good place to start might be to understand how/why a MEMORY is required to time things.

    Memory is required to recall the original beginning, duration, and end of a past event.

    You even need a memory to acknowledge that events are occurring.

    Without memory we would not be able to "re-cognize" anything at all.

    As Anil Seth posits: "we create our reality from the inside out as much as from the outside in"

    Sometimes our memory fools us;

    A rectangle of the same color has been drawn connecting the two areas of the image.

    This illusion is caused by a false memory, an ancient survival mechanism (engram) to "recognize" possible danger hidden in the shadows.

    p.s. IMO, this is very much related to the function of microtubules in the brain.

    I believe this is also responsible for the apparent fast (time flies) or slow (time crawls) subjective passage of time in our interactive experience with the environment.

    I don’t think there is anything that exists that doesn’t have a memory

    Max Tegmark has a nice analogy.

    He shows his wedding ring that is inscribed with his wife's name and demonstrates that solids do have capacity for long term memory.
    Then he draws his wife's name in a puddle of water and demonstrates that liquids have very little capacity for memory.

    David Bohm demonstrated that very viscous liquids have capacity for long term memory if the inscribing is done slowly without causing turbulence.

    Every object in the universe and the universe itself has a mass energy history/memory recorded in its current physical configuration. Everything is a product of its history.
    For us to start measuring stuff we need a 3rd party memory and processor?

    This maybe interesting . You can buy time .

    Why is it necessary that time must exist apart from physical existence"?

    Why can there not just be a timeless permittive condition (dimension) that simply allows for physical phenomena to occur chronologically and for arbitrarily measurable "duration" to emerge as what we call "time".

    Note that "standard time" is a derivative of a physical phenomenon (caesium decay).

    Time is only measurable from physical dynamics, just like mathematics.

    Is time based on math?

    Jun 22, 2019 — Among physicists, there is no real doubt that time does really, truly exist. It's a measurable, observable phenomenon.

    If that is the case, then do mathematics exist? It is a measurable, observable phenomenon!

    So how big is math?

    How is that even possible?

    Right, that is the question.

    Does colour exist apart from physical objects?

    These are all the same question.

    All these phenomena are emergent properties of physical dynamics and mechanics.

    Does wetness exist apart from dry H and O atoms?

    Time does not exist except as an emergent result of duration of physical relationships.

    du·ra·tion, noun
    1. the time during which something continues.
      "a flight of over eight hours' duration"

    That's pretty much what I said on Page 1.

    Yes, pretty much, and I agree....
