Is Time objective in itself ?

Unlike Einstein, I am not a believer in objective reality. But time being relative to an object in no way limits its existence to that object. They always use the trampoline metaphor and it feels like unless their is a weight on the bouncy house that it doesn't exist, but it does, just with ambient pressure from the whole universe.

An unattended bouncy house moves very slowly in time, but it moves.

There has to be a name that describes the substance between two seconds. Since everything is not happening instantaneously, there is a metaphysical dilemma: "what iseasurable universal exists between every particular second? Socrates called it "moment."

'Time' exists in the imagination!

Only!

Completely subjective, like everything else perceived by the unique individual.

Sometimes it seems to plod, sometimes seems to fly.

All in your imagination!

Outside of human observation time does not exist. Time is an arbitrary unit of measure based on the earth's rotation around the sun, and has no inherent reality. 12:00 p.m. in New York City is not noon in Tokyo. What "time" is it on Mars? Time is an imaginary concept imposed on the external world, which is timeless. Typically people think of timelessness as suspended animation, which is not possible. The mind is programmed to observe sequential change in form and matter, but it is not 'caused' by time.

All units of measure are arbitrary selective points of observation as a guide or reference, not an actual 'thing'. It is like imagining two points on a wall and drawing a line to connect them. There are no points or line anywhere on the wall. Adding another point and connect them to the other points creates a triangle on an imaginary two dimensional plane. Imagining a fourth point and connecting it to the rest of the points results in a pyramid as a three dimensional form. The form has not reality except in the minds imagination

Time is not a directly objective observation but a constantly subjective one. Time is how we measure change in a system and can have different measures under different circumstances, such as relative speeds or temperatures. There may be other circumstances which can alter the "flow" of time too.
