It's not a word, but more a general idea: the Captain/someone else/ the entire ship is diseased/in an area with lots of radiation, and the doctor warns that they've got 17 hours, 47 minutes left. After 17 hours, 46 minutes, nothing is the matter, and there will be no long-term damage, if there is even any damage at all, but after 17 hours, 47 minutes, they will just drop dead.
or hwo about on Enterprise when Trip and Reed are on the Romulan ship and Trip's being irradiated and dying, then they "turn it off" and he's fine
Fortunately, I watched ENT from downloads - but I rewatched "Broken Bow" recently on SciFi and was shocked at all the stuff they censored. "You have no idea how much I'm restraining myself right now from knocking you on your ass" became just "You have no idea how much I'm restraining myself right now", and they even removed the phrase "stinky feet".
