A very good argument can be made for time as an effect of motion. For one thing, it isn't the point of the present, moving past to future, as it is change, turning future to past. Tomorrow becomes yesterday, because the earth turns.
There is no literal "dimension" of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.
So time is asymmetric because it is a measure of specific actions and action is inertial. The earth only turns one direction.
Different clocks can run at different rates simply because they are separate actions. Think metabolism.
As an effect of motion, time would have more in common with temperature, pressure, color and sound, than space. Think frequencies and amplitudes.
Given that we are mobile organisms, we have a sequential process of perception, as a necessary function of navigation, then as humanity, we have a narrative based culture, so the presumption of time as this flow from past to future is pretty deeply ingrained. Yet what are the implications of reality as only the present?
For one thing, energy is "conserved," because it is the present. Its changing configuration creates the effect of time. So the energy, as process, goes past to future, while the patterns generated go future to past.
Consider this in terms of a wave; The energy is what drives it, while the patterns, the fluctuations and undulations, frequencies and amplitudes, rise and fall, future to past.
Keep in mind that what we "see," are the forms, rather than the energy.
As these biological entities, we have the digestive, respiratory and circulatory systems processing the energy driving us on, while the central nervous system sorts through and further condenses and organizes the information precipitating out. Which naturally creates somewhat of an intellectual bias toward the forms over what manifests them.
Does this go to some of the issues currently bedeviling theoretical physics? Trying to understand the reality in terms of the forms we comprehend, yet it seems somewhat slippery in ways our tools of observation cannot grasp? Yes, it's information all the way down, but it's energy all the way up.
Galaxies are energy radiating out, as forms coalesce in. Energy toward infinity, while form toward equilibrium. Both entropic and diametrically opposed.
I realize the field is way too wrapped up in the mazes it has concocted, but just putting this out there, as a logical observation of time as effect.
