In physics spatial distance d is a product of velocity v and time t : d = v*t .
Mathematical formalism x_{4} = i*c*t
confirms that in Special Theory of Relativity forth
coordinate x_{4} is spatial too. x_{4} is composed out of c light speed, imaginary number i
and time t that represents "thick" of a clock. Time t obtained with clocks describes
numerical order of material change t_{0} ,t_{1} ,t_{2} .......t_{n}. Clocks are reference systems for
measuring frequency, velocity, numerical order of material changes that run in space.
Time t x_{4} is running of clocks in space. Clock/time is a measuring reference system
for measuring physical events that are running exclusively in space and not in time.
Light speed c of light motion is a fundamental speed in the universe on which is
calculated basis unit of time "Planck time". This view explains some recent
experiments which confirm that time t of physical event can be zero.
