• (It's not exactly what you asked, but here's a related problem.)

    SQL Server (and its various components, including Reporting Services) have a default date format that is assumed anytime another format is not specified. It's tied to the languages installed, and there are system stored procs that will tell you which is the default. If more than one language is installed then each user account may have its own default language (and date format). You can set the dateformat in SQL if you want, or just adjust to the default language/fomatting on your box.

    There are countless blog and support pages dedicated to the topic. Just put in DEFAULT DATE FORMAT in the search box on this page. Here's one of the first ones that comes up: Changing the default date format of SQL server 2005.
