(This is intended to be continuous with McTaggart’s distinction.) B-occurring entails A-occurring: if something occurs at a temporal B-location t that is now, it occurs now. But not vice versa. Something can occur now without occurring at a temporal B-location t that is now. Something can, that is, A-occur without B-occurring. Now define A-simultaneity as occurring “at the same now”. B-simultaneity, by contrast, is having the same temporal B-location in ...
