How do I *not* supply a column for update in EF?

I am sure I am not the first one to struggle with this.

I am using Entity Framework 1 (VS2008) and one of the columns in the table is ModifiedDate. It has DefaultValue in SQL Server (getdate()); so I would like to leave i开发者_开发问答t the DB to do the generation. However, generated SQL has INSERT (... ModifiedDate) VALUES (... null), and the default value doesn't get inserted.

Is it possible to not specify this column at all?
