Thanks for the question. For a fixed rule like that, you're right, a date adds nothing. What the dates are really for is letting the AI live on the same clock as you. A model has no sense of time on its own, so it can't tell whether we last talked five minutes ago or two days ago. My setup injects the current time plus a timestamped index of past conversations into every turn. That way it notices on its own that it's been two days and asks how I've been, and it can answer "what were we working on yesterday?" The hook isn't in the repo yet, but I'm happy to add an example.
