When generating a sitemap from org-publish with the anti-chronological and list options set, i noticed that the order of files wasn't as i expected.  I wanted the order to be in the order i specified with DATE keywords in each individual file.  I modified org-publish-sitemap-default-entry to include the date as well:

(format "%s: [[file:%s][%s]]"
        (format-time-string (car org-time-stamp-custom-formats) (org-publish-find-date entry project))
        entry
        (org-publish-find-title entry project))

All the dates shown were the mtime of the files, rather than the dates i specified with the DATE keyword in YYYY-MM-DD format.  Looking at org-publish-find-date, it seems that the let binding successfully pulls the date from the file, but it looks like #1=(#("2024-05-28" 0 10 (:parent #1#))).  My elisp skills aren't great so i find what this means quite difficult to understand, but the following cond clause seems to not work because (assq 'timestamp date) always returns nil.

I've tried running this with emacs -q and get the same issue, and also have updated to the version of org in elpa, and get the same issue.
