  time T
       
          /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.
