Time and space are shown to have very different properties, both from each other and from that of the macroscopic world, when they are investigated at distances of the size of elementary particles; even the definition of time is in some doubt in such a case. Space reflection is violated maximally, but time reversal is not. Indeed it may not even be violated at all, but if it is not then causality is violated over such short distances. In any case the basic laws of physics will have to be changed; when the details are finally worked out the concept of time will be altered ineradicably from the common sense one.
