It should also be noted that the functional time results from motion as a reason for becoming. The becoming should be understood as a substantial change associated with the emergence of something qualitatively new as well as the emergence and disappearance of objects and their states, along with their transformation into other objects and their states. The becoming that makes something that has not existed become existing.
The objective and real time is called functional due to the very existence of time and all its properties depend on successive qualitative changes in specific physical objects resulting from the realization of their potentialities and their interaction with the environment.
Thus, the temporal rhythm and current durations of successively changing states of an object or a process depend on those of the successive whole new changes in the physical objects or the process that determine them.
Since time as it is does not exist, beyond physical objects or processes that disappeared upon the embodiment of their physical potentiality in subsequent objects, their proper time is deprived of the physical meaning.
For being non – substantial, time must emerge with specific physical objects or processes before it can exist. Given that the functional time is determined by the period between the emergence of real physical objects until they disappear (upon the embodiment of their physical essence into other subsequent objects). Then, as already mentioned, new subsequent physical objects or processes determine their proper time in which they exist due to the non – substantialness of time.
The objective and real, functional time is determined by all objects or processes in nature, from an elementary particle to the cycles of expansion and compression of the Universe, if it switches back, since in this case the cycles of the Universe emerge and terminates.
Even if the Universe, that embraces all the objectively existing world, switches back, it does not determine time, since time is always finite, while, according to all scientific and practical data, the Universe is uncreated and indestructible. In this regard, the concept of time is inapplicable.
Alternating days and nights cannot be considered the functional time, since they are a consequence of the mechanical rotation of the Earth.
