Just wondering, when creating FieldPersistenceInfo for DateTime, why do you set Scale and Precision to 3, 23? If I create a DateTime in SQLServer, scale and precision are set to 0, 0 automatically. Or are these values for another database type?

I just pass on what the views in sqlserver offer me . I use every value always, to avoid having logic in the code which first checks the type and then sets the parameters required. I just set all the parameters and let sqlparameter figure it all out.
