Aak!  No!  Lojban list once spent a >year< discussing relativistic spacetime
and the so-called "fourth" or "oblivious" tense.  Lojban tenses are subjective:
they refer to the viewpoint of the speaker, not to "objective" time
relationships.

(If you like, I can send you about 150K of stuff on the subject.)
