On the Grunge template there is a class 'floatleft' or 'floatright' that will put a background around a picture, shows like it's taped to the picture, also shows a torn sheet taped to the opposite side with the date. That date format is different than the default system date, which in my case is also showing on the article. The Article date shows correctly. (displayed as formatted in the parameters.ini file). It's the torn sheet format that is different, where is that coming from?
You can change the date format to frontpage, sections, categories and articles by going into the appropriate template html folder. (same as how I directed for your frontpage) Some files may not have the LC# call, instead have the direct date format setup.
