The universe is in a continuous change. A change n gets transformed into a change n+1, the change n+1 into a change n+2 and so on. Clocks measure a frequency, velocity and numerical order of change. Changes do not occur in time, changes occur in space only. Time is not a part of space. In the space there is no past and no future. Past and future belong to the inner time that is a result of neuronal activity of the brain.
