My variable is this one: rcd-temp-buffer-name ⇒ "RCD TEMPORARY BUFFER"

And I rarely save it as such, but files are connected to temporary
buffers. It is very handy, as it is temporary note, and if I wish to
exit Emacs I will be notified there is maybe still something to be
saved.

You are right, your suggestion is much better for sorting and visual review.

(defun rcd-temp-buffer (&optional prefix name mode)
  "Generate new temporary buffer."
  (interactive "p")
  (let* ((file-name (concat rcd-temp-file-directory 
			    (format-time-string "%Y-%m-%d-%H:%M:%S-")
			    rcd-temp-buffer-name
			    ".txt"))
	 (buffer (or name (concat "*" rcd-temp-buffer-name "*"))))
    (switch-to-buffer (generate-new-buffer buffer))
    (setq buffer-file-name file-name)
    (if current-prefix-arg
	(let* ((mode (completing-read
		      "Mode: "
		      (map-keys rcd-temp-buffer-modes) nil t nil
		      'rcd-temp-buffer-mode-history)))
	  (funcall (intern mode)))
      (funcall (intern (or mode "fundamental-mode"))))
    buffer-file-name))
