Welcome

ChatGPT doesn’t track time or complete tasks after a delay. If it said “I’ll take 3 hours,” it’s a hallucination, the model guessed an answer based on patterns from human-like conversations.
It can only respond instantly and cannot actually wait or perform tasks over time.
It misunderstood your question and gave a human-like reply it can’t follow through on.
Hope that helps!
