1. 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 favorite 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.
