I'm trying to merge all of my text-based notes into Notes.app. My notes are all over the place: some in text files, some in email drafts, etc. I can of course just copy and paste the text of such notes into Notes.app, but then their date created and date modified will be as of the time I copy and paste them in, rather than when I actually made them or modified them, and I'd like to retain the original date data.
I don't believe there is a way to change this directly in Notes.app, but is there a way to change the dates in the files created by Notes.app? If so, how?
