Format for date field

On a page that has a date field with a short date format of dd/MM/yyyy, an example entry might be 20/04/2009. However, if you change the entry to a value such as 20/04/09, more help appears. When you submit the entry, the value changes to 20/04/0009, rather than 2009.

You can successfully submit the entry by typing the value with the expected format of yyyy for the year. For example, type 2010.
