Digital Signature in BIOS File Properties

This question concerns the timestamp that appears in the Digital Signatures tab in the File Properties of a Dell system BIOS file. Does the timestamp tell you that Dell did not make any additional changes to the file after the date/time listed in the timestamp field?
