It's a great question, sir.
I'm not a statutory expert. I think that's probably the date at which the act would come into force. Presumably it would start these clocks, because if you recall, sellers are required to keep track of when a customer purchased something. All of a sudden there is going to be a clock associated with every customer, and the clock presumably would have to start running at the time the act comes into force, just so we could keep track of such things and not have to try to go back and determine where the clock is.
