The problem is that your expression basically defines a 'contains'-type
search, so it's matching the first 10 characters as required but then
simply ignoring that last, 11th character because there's no requirement
regarding it in the expression.
Try this instead:
^(\d{4}-\d{2}-\d{2})$
The ^ anchors the matching string to the beginning of the string, while
the $ anchors it to the end, which effectively forces the expression to
match the entire string, disallowing extra characters before or after it.

Bob
