One thing you could do is have your day roll over at, say, noon; and then you can check in the next day instead (at the cost of having to remember what you did before noon today, until afternoon). I agree, it's not perfect. Time travel is a tricky issue, because if you're in a party and taking part in a quest, your missed dailies hurt your party members. So if you go back and say "actually I did that thing", ideally it needs to restore health to them, after some of them might have died, etc.
