Also short revue of our investigations of local-time effect existence for distances from 15 km to 500 m are presented. Besides investigations of the minimal spatial scale of local-time effect existence the paper presents investigations of the named effect for time domain. In this relation a structure of intervals distribution in neighborhood of local-time peak was studied and splitting of the peak was found out. Further investigations shows second order splitting of local-time peak. From this result arise a supposition that space-time heterogeneity, which following from local-time effect existence probably has fractal character. Obtained results lead to conclusion about sharp anisotropy of space-time.8 pages, 5 figuresGeneral Physicstext
