  The hypothesis of the random flow of time is considered. To do this, the
concepts of microscopic random time and macroscopic mean time, as well as
random modular time are introduced. The possibilities of experimental
verification of the hypothesis of the random flow of time are discussed. The
possibility of interpreting the time-like fifth coordinate (introduced by V.A.
Fock) as absolute time is considered and the question of the reality of
absolute time is discussed. The absolute time, which manifests itself as the
proper time of the particles, is assumed to be random.
