Not sure what you were getting at however as far as the article under discussion indicates (here is the quote)
Once the company sets the record date, the stock exchanges or the National Association of Securities Dealers, Inc. fix the ex-dividend date. The ex-dividend date is normally set for stocks two business days before the record date. If you purchase a stock on its ex-dividend date or after, you will not receive the next dividend payment. Instead, the seller gets the dividend. If you purchase before the ex-dividend date, you get the dividend.
However since I am holding, for awhile at least, I have paid very little attention to the ex-date. It doesn't affect me. I have the shares I'm holding and I have shares I'm flipping (and getting divy for) I will sell each holding and flipping shares when the pps hits predetermined sell points and will buy back in at again predetermined points or as I feel like it :) which ever comes first.
