Clocked and perceived time
In the previous chapters, we have addressed the question of performance as it is measured by objective time. Objective time is measuring, by the means of a tool that divides, in equal units of measurement, a duration between an imminent future and an imminent past whose parts are in a continuous persistent flow of being.
This definition of objective time shows us that time is the effect of a movement of existence that takes us from an undetermined future to the state of a frozen past by the means of a constant present. It is objective inasmuch as a third-party being is used as a witness to this passing of being from one state to the other by dividing it into equal units of measurement. This is the reason why objective time is often named clocked time, as it refers to the concept of dividing time into equal units of measurement (for example, seconds, minutes, hours, and so on). Obviously, the field of science that studies objective time is Physics.
