time is a direct function of motion over distance, irrespective of perception.
Time is, indeed, a function of motion over distance. We humans percieve a day to be 24 hours, weeks and months to be as they are due to the lunar cycle, and years to be 365 days all due to our measurements of the motions of our earth, moon and sun.
However, time is also perception. We have a different perception of time when we are children, for example, than when we are elderly. We have a different perception of time when we are busy and rushed than when we are lazing about.
Our perceptions of time are fixed to a 24-hour day, a seven-day week, and a 12-month year, as well as to our practice of numbering years, and by the knowledge that our lives are finite.
If we were born on an orb that does not rotate around its axis and/or rotates around a huge planet instead of around a star, our perceptions of time would be different because we would measure it differently.
