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.
A status of T can mean they are painting, removating, going on vacation, a fmaily emergency etc where the sellers does not want to show the home for a given period of time. Sometimes it can mean that they changed their minds completely, and are just waiting for the listing to expire, so they just suspend showings till then.
