Time is something that is created. By people? Yes. But also by all processes at the moment of change.
Calling it ‘needs’ implies a consciousness – I’m not going *that* far.
But, as an electron hold “needs” to be filled (in that sense of needs), it gives to itself what it needs from a nearby electron that is “willing” (for lack of a better word – no consciousness here that I’m speaking of) to give itself up to be taken.
That’s communication of information, in an information science pov.
And the transaction is what creates time.
We make time to do things. We make lack of time to do things. It’s not micro vs macro. Look at a bottle with a paper label on it.
The paper is creating its own time as it exchanges with the environment. It has its own cycle of deterioration. The glass bottle has its own cycle of deterioration, which is different.
They will consequently age differently from our perspective. But our perspective is not absolute either. We “hang time” off of the stars, which we have embedded in the activities of two cesium atoms exchanging an electron (if I remember right). But it was calibrated by how we measure time traditionally by the star formations. Coordinates.
But this is merely a convenience. Stars are old and we are young and so it works “close enough” for our purposes.
But being practical doesn’t make it true. Just practical.
