Google Analytics is a good platform for statistics, but you really can't drill down to specifics and get hourly breakdowns of your conversion data. That's okay -- almost -- because there's a workaround that SteveLaLonde presents at Search Engine Watch Forums.
He says that he implemented a duplicate web site profile in Google Analytics and then applied a filter which shows AdWords data only. Of course, it doesn't you real detailed data, but you can gauge overall trends.
As always, it would be great if Google would actually incorporate this data without a workaround (hint hint, Google), but if you're looking for something to hold you over until Google actually does enhance their Analytics, this is a reasonable solution.
