[en] The possibility is discussed of using right and left Feynman clocks (made on the base of parity nonconservation) for practical realization of anisotropic time-space. Characteristic properties of anisotropic (noncommutative) planimetry are considered. The difference between rotation in the Euclidean plane and rotation in the Minkowski plane is emphasized. It is noted that from the Minkowski space symmetry relatively inversions and reinterpretation principle the existence of antiparticles (as objects with negative energy moving back in time) follows. Attention is paid to the interconnction between space and time inversions. A possible nonconservation of leptonic charge in K_l3⁰-decays is indicated as a consequence of the T-invariance violation. 10 refs.; 4 figs
