he first stage of time abstraction is duration. This entire process occurs from becoming (changes). Duration is the interval between a beginning moment and an end. The second stage of abstraction is the establishment of time units. For example, the duration of the Earth's rotation is one day. After a mathematical procedure, the day is divided into 24 parts which are made up of hours.
The third stage of time abstraction is the physical and tangible symbol of the clock.Although the abstraction of time is carried out by the subject, it is objective and based on the becoming. Becoming is the continuous succession of irreversible changes that go from the past to the future through the present. Becoming is concrete and tangible. Time exists in clocks and in periodic phenomena.
Through these three stages we arrive at the knowledge of time.
