bram85,
magit-find-file
allows you to open a file at a certain revision, which could be a (relative) timestamp. Notation: HEAD@{3 days ago}.Using these bits, I wrote a small #emacs command that displays a file at a certain moment, chosen with the built-in calendar.
(defun bram85-magit-find-file-as-of (datetime) (interactive (list (org-read-date))) (let ((rev (format "HEAD@{%s}" datetime))) (magit-find-file rev (magit-read-file-from-rev rev "File: "))))
