"T minus zero" means "out of time."

This comes from a countdown convention used in by both the American military and NASA.

Generally, it is used when counting down to a major event that will happen at a specific time.

Mathematically, T is time, minus whatever amount of time is left until the event happens.

If the News Years ball is dropping in 10 minutes, one could say "The ball is dropping in T minus 10 minutes and counting!"

Therefore, "T minus zero" means that there is no time left.

I was working on my term paper all night for my morning class, and all the sudden I looked up at the clock and realized I was t minus zero.

What Mission Control in the Houston Space Center never says. They stop after T Minus 1 because T Minus zero is not significant in the countdown.

There is no time left and you need to make a decision. To fuck or not to fuck. That is the question.
