My narrow physicists' answer is that conciousness doesn't just happen "now", it happens _here and now_ -- and that isperfectly well defined in all relativistic frames of reference. A broader -- and much more speculative answer -- is that concious experience "is happening" (English tenses are not approriate for this discussion) all over the time-space. But at each point along the trajectory (history) of an intelligent being, there exists an unsually coherent, understandable description of a part of that experinece. Our catch-all description for such descriptions is "what Mr X is experiencing now".
