Time is a process by which nature prevents everything from happening all at once.
time T /ti:m T/ n.
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 Modhur’s Canteen at time T+1” means, in the context of going out for dinner: “We can meet on campus and go to Modhur’s Canteen, or we can meet at Modhur’s Canteen itself a bit later.” (Modhur’s Canteen is Dhaka University restaurant in Dhaka that was a favorite with students.) Had the number 30 been used instead of the number 1, it would have implied that the travel time from campus to Modhur’s Canteen is 30 minutes; whatever time T is (and that hasn’t been decided on yet), you can meet half an hour later at Modhur’s Canteen than you could on campus and end up eating at the same time. See also since time T equals minus infinity.
2. a period of time considered as a resource under your control and sufficient to accomplish something; “take time to smell the roses”; “I didn’t have time to finish”; “it took more than half my time”. .
