  It is shown that the Schrodinger equation is a byproduct of more
deterministic Boltzmann-like equation. All physical information is derived from
the solution of this equation, which is a function of space and momentum. The
additional terms in this equation, when compared with the classical Boltzmann
equation, asserts that the particle should be broadened over the time axis,
i.e., it is partly present at the past, the present, and the future. The
solution of this equation itself is nonlocal. This solution requires an
especial time coordinate that is different from the usual time parameter
entering into the formalism of quantum mechanics. This time coordinate is
hidden in the structure of wave function. It is substantiated that the mixed
state is a natural result of time broadening. Furthermore, the interaction
between an object that is broadened in time and an observer that has a very
narrow time-width leads to the collapse of wave function.
