Unlike classical physics, quantum mechnanics is sensitive to mistaken choice of chiralities or time-arrows of local reference systems. Quantum correlations between distant electron spins, for instance, would reveal a mistaken local chirality. Local polarization measurements and classical communication enable the distant partners to compare their local chiralities. Local time-arrows can be calibrated in a similar way.
