Three questions about time
1- What do clocks measure?
Clocks measure continuous intervals of equal duration, that is, time. When the clock synchronizes with the rotation of the Earth, it tells us the time of day. Time is the tool (periodic becoming) with which we measure the duration of things and determine when events occur. Time and the clock combine to give real existence to the former.
2- How does time work?
Time is the interval between two sequential moments, one of which is the beginning and the other the end. Time interacts internally with matter causing development, aging, material deterioration and the replacement of the old by the new. In the Theory of Relativity, high speed interacts with the matter of the moving body causing time dilation.
Stopwatches and timers also measure time.
3- Why time is magnitive?
Time cannot be seen, it cannot be felt, it cannot be touched, but it is measurable, for these reasons time is magnitive. That is why we conceive time as a physical measure or magnitude. Some authors believed that time was simply a measurement, including Aristotle. This great thinker believed that time exists because there is an observer who measures it. Magnitive time is objective, subperceptible and measurable.
