Here's a way to think about time;
As these mobile organisms, this sentient interface our body has with its situation functions as a sequence of perceptions, in order to navigate, so our experience of time is as the point of the present, moving past to future. Physics codifies it as measures of duration and correlates them with measures of distance, aka, one dimension.
The evident reality though, is that activity and the resulting change turns future to past. Tomorrow becomes yesterday, because the earth turns. Duration is the present, as the events come and go.
There is no physically real dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.
Energy is "conserved," because it manifests this presence, creating time, as well as temperature, pressure, color and sound. Frequencies and amplitudes, rates and degrees.
Ideal gas laws correlate volume with temperature and pressure, but we don't consider them extension of space, even though they are as foundational to our emotions and bodily functions, as sequence is to thought.
Different clocks can run at different rates simply because they are separate actions. Think metabolism.
That society is about synchronizing the community into one larger social organism, using the same languages, rules, measures, it might seem there should be one universal flow of time, but that would be like only one frequency.
Nature is so diverse and yet integrated, because everything doesn't march to the beat to the same drummer. Multicultural, not monocultural.
Time is asymmetric, because it is a measure of action and action is inertial. The earth only turns one direction. Entropy is a second order effect and not one of the regular cyclical actions used to measure time.
Energy goes past to future, because the patterns it generates coalesce and dissolve, future to past. Energy drives the wave, the fluctuations rise and fall.
Consciousness also goes future to past, while the perceptions, emotions and thoughts giving it form and structure go future to past. Though it is the digestive system processing the energy, the nervous system sorting the information and the circulation system as feedback between them.
Consequently the intellectual tendency to consider reality in terms of the patterns expressed as signal and the processes generating them as noise.
Galaxies are also energy radiating out, as structure coalesces in.
As for three dimensions of space, that is a mapping device, like longitude, latitude and altitude. If all physical properties are removed from space, it would have the remaining qualities of infinity and equilibrium. Which is implicit in the fact that the frame with the longest ruler and fastest clock would be closest to the equilibrium of the vacuum.
So the energy radiates out, toward infinity, as the structure coalesces in, toward equilibrium.
Zero to infinity.
