It is important how we measure it. Time Measurement/Measurement: one possibility: use something that changes periodically. History: to be able to use the day as a measure, they had to make understand that days are not always of the same length; a different instrument was needed for that, e.g. an hour glass. But with that they had not yet proven that they are periodic! >Covariance. We can simply say that our definition of time is based on the repetition of an obviously periodic event. >Measurements, >Definitions.}, note = { Feynman I Richard Feynman The Feynman Lectures on Physics.
