It all depends on the way you interpret "valid until". Anyway, I don't have to take your word when you're telling me you are in Belmont, and I don't have to take it either when you're stating that this will not change. I can believe that you think *in good faith* to be in Belmont, while in fact you are a prisonner of the Matrix in Palo Alto. Silimarly, I can believe as well that you thought in good faith, at 11:46, that you would still be in Belmont untill noon. I don't know how to manage that kind of uncertainty, e.g. in SPARQL queries. All I'm saying is that those uncertainties exist for statements ; they can exist for metadata about statements as well, and we have to live with that. pa
