Thanks for your helpful hint. I finally got a solution:

#+begin_src emacs-lisp
(add-to-list
 'org-agenda-custom-commands
 '("c" "Tody [c]locked tasks."
   ((agenda ""
            ((org-agenda-ndays 1)
             (org-agenda-span-1)
             (org-agenda-use-time-grid t)
             (org-agenda-include-diary nil)
             (org-agenda-show-log (quote clockcheck))
             (org-agenda-clockreport t))))))

(let* ((org-agenda-sticky t)
       ;; Run it in background instead of switch to agenda buffer with `save-window-excursion'.
       (_ (save-window-excursion (org-agenda nil "c")))
       (origin-buffer (current-buffer))
       (origin-buffer-point (point))
       (agenda-buffer (with-current-buffer "*Org Agenda(c)*"
                        (buffer-substring (point-min) (point-max)))))
  (print agenda-buffer))
#+end_src

So that I can record those into into Diary.
