Newsflash: Time May Not Exist
Most of us tend to think of time the way Newton did: "Absolute, true and mathematical time… flows equably, without regard to anything external." But as Einstein proved, time is part of the fabric of the universe… something that's independent of the universe. In fact, says Lloyd, clocks don't really measure time at all.
Time is a byproduct of society. To ensure that everyone behave like sheep, simply put everyone on the same time-table.
