Narrative:

During preflight I noticed that the efb (electronic flight bag) data base was not current. The data was out of date by one day. I advised the captain that the efb was not current and mentioned that our paper charts were current and in my opinion; they would supersede the efb. He said not to be concerned about the efb.
