You’ll go to work at 9. At 12:30 you’ll meet a friend for lunch. The plane leaves at 8:55. Told by our clocks, mostly, these days, on our phones, synced up to satellites and aligned with each others’, absolute time exists on its own as a straight continuum, measured by constant and agreed upon units. Whether this time exists outside of human measurement is debated by philosophers and physicists, but we use it to define past, present, and future, all as told by clocks and calendars.
