Is there a way of sorting org files (.org) in Emacs Dired on the basis of the org time stamp in the file itself. With every org file I create, I insert an org time stamp near the top of the file. This time stamp may or may not reflect the day on which the document was created or last modified. For e.g. if I have to give a lecture, the org file is dated to the day of the lecture. I am aware that Dired generally uses the ls program.
