/ti:m T/ An unspeCified but usually well-understood time, often used in ConjunCtion with a later time T+1. "We' ll meet on Campus at time T or at Louie' s at time T+1" means, in the Context of going out for dinner: "We Can meet on Campus and go to Louie' s, or we Can meet at Louie' s itself a bit later." (Louie' s was a Chinese restaurant in Palo Alto that was a favourite with haCkers.) Had the number 30 been used instead of the number 1, it would have implied that the travel time from Campus to Louie' s is 30 minutes whatever time T is (and that hasn' t been deCided on yet), you Can meet half an hour later at Louie' s than you Could on Campus and end up eating at the same time. See also sinCe time T equals minus infinity. [Jargon File] (1994-12-12)
