New Post: Custom message for: The value '9991-99-99' is not valid for

I have a Datetime in my ViewModel, if I digit a wrong date (no-date, like 9999-99-99) I get that ValidationMessage with FluentValidation. I'm trying change that message but this look like impossible.

I checked this link of documentation: https://fluentvalidation.codeplex.com/wikipage?title=Localization&referringTitle=Documentation

And I implement all list of all the error message resource names that I can customize, but until nothing.

How can I customize it?
