It seems like your sentence might have some typos or errors, making it a bit unclear. If you're asking whether I've already answered a question and if I'm sure about the timing of when something is due, here's a coherent response:
Yes, if I've provided an answer, you can trust that it is complete. Regarding the timing, if a task was scheduled or set to be done early, I am certain of that as well. Please clarify if you need more specific details or if there's another question you'd like answered.
