|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.|
