Time is a favorite topic of mine too. It began when I read Kant and his conclusion that ~time is an
a priori condition of all inner experience [i.e. that time is something that the human mind projects out into the world]. Buy into that as the strong scientific claim that there is no independent process of time independent of our experience of it or not...there's no denying that our systems for measuring and expressing time are artifacts of human culture and that scientific definitions are
ex post facto.The idea that noon is not when the sun is on the meridian and a mere footstep east or west changes time by an hour with all the force of the state's instruments of violence [1] is a mark of tyrannical authority. The Gregorian Calendar is a product of a system in which people act upon a belief in a divine mandate for their authority.
Which brings me to the objection that was not addressed. I don't want to cede my freedom to a theocracy even dressed in technocratic robes. My time isn't yours to decide.
