Or, more specifically, "your brain" seems to be the only thing using
time since your brain is interpretting the images. So you might say
that time is a fabrication of the brain.

But Einstein was able to utilize time as simply another coordinate of
space and produce very elegant and verifiable results. That suggests
"the Universe" utilizes time, too, and not just space.

Thanks to man's ingenuity, he can also build counters to control other
machines. However, machines merely do man's bidding (we hope) thus I
would agree, "time is a fabrication of the brain." The brain only
knows now, it remembers now-past and imagines now-future.

I am not saying there is no real something we call time, I just don't
see anything specified as a timekeeper that does anything more than
count standard units of energy or distance.

But, my brain is not subject to calibration, it is a poor device to
set a luncheon date by or witness 2 horses run. If I have hot date
for lunch, I will probably arrive early, if it is with my accountant,
I may be late. If I like one horse and find the other ugly, my
imagined passage of speed is altered (suppositions). The perceptual
apparatus (cones, neurons, etc) will be providing their responses to
the stimuli based on their chemistry.

Being useful is not proof of existence.

Time is a convention long ago accepted to allow coordination of
behavior. I would bet the sun and moon were the original time
keepers. There similarity to clocks? Their motion through space was
dependable enough for 2 people to meet at high noon, or full moon and
not keep each other waiting too long.

I am glad there is interest in the thought about time. I have
wondered alone for many years.
