I missed that.
Further, `org-export-file-name' gets called before `org-export-as' so there is
no hope of using export hooks or filters or other gambits like that.
I don't see a clean way to do date stamp the file name without writing your own
export-to-file function that handles date-stamping the file arg sent to
`org-export-to-file' or replacing/advicing `org-export-file-name' to do that.
