It's not the intent to affect you negatively. It's purpose is to give people until the ship-by. By that I mean it's a program that all it does is read something like, 'order due to ship by X date. Check on X date. Did order ship, Y or N'. As long as it shipped before or on that date, it qualifies. There is nothing in the program to say, 'did the order ship early?'
That's why it works the same for messages. Because you have 24 hours to respond, if you get a message on the last day and its response is required on the 1st of the next month, it won't matter if you respond in 2 minutes or 23 hours. The program doesn't check if something is done early, only if it's been completed by the end of the required time.
