  I've never had an issue like you describe with dates before. I've always output them in the csv in Y-m-d format and that has worked as expected. I should have been more precise and said if your data isn't using the set of features described in the article there isn't a big difference. Not all data has dates, time durations, percentages, and number formatting.
