I have been annoyed by official definitions of time from many Google searches and decided after listening to Sean Carroll's podcast to write my own. Here is what I did so far:
What is time? A state that changes.
What does time look like? It is perceived as a non-spatial continuum of changing states where each state has the most infinitely small differences compared to any other state in the continuum.
The arrow of time? A state in high entropy is not changing, and so only a state that has low entropy can be a state that can change. Any changing state therefore is perceived as a state changing with linear direction governed by the entropy of the continuum.
Please let me know if I used any time-like words, or you have some better definitions.
