  A new concept of internal time (viewed as a scalar temporal field) is
introduced which allows one to solve the energy problem in General Relativity.
The law of energy conservation means that the total energy density of the full
system of interacting fields (including gravitational field) does not vary with
time, thus being the first integral of the system. It is demonstrated that
direct introduction of the temporal field permits to derive the general
covariant four dimensional Maxwell equations for the electric and magnetic
fields from the equations of electromagnetic fields considering in General
Relativity. It means that the fundamental physical laws are in full
correspondence with the essence of time. Theory of time presented here predicts
the existence of matter outside the time.
