The Japanese intended that the message cutting off negotiations be delivered just before the attack. Since it was Sunday morning in Washington, the Japanese embassy had to call the code clerk to come in.
Since the USA had broken the Japanese diplomatic code, and had people on duty all the time, the USA had the full text in President Roosevelt's hands before the Japanese ambassador delivered the note. And keep in mind that communications between Washington and Honolulu weren't the simple matter they are now. You couldn't just dial 1+.and be connected.
