Sure!

I did this already 😉 thanks

Actually I used 
(defun my/org-add-timestamp-on-heading ()
  (save-excursion
    (org-back-to-heading)
    (org-edit-headline (format-time-string "<%Y-%m-%d %H:%M>")))
  (insert " "))

(add-hook 'org-insert-heading-hook 'my/org-add-timestamp-on-heading 'append)

Thanks, I try that out.


A last question though.

Now if I want my headings look like 

* <2025-02-02 08:58> Second entry 

* <2025-02-02 08:53> First 

* <2025-02-02 08:56> third 



Is there any way to sort these heading with respect to the timestamps from oldes to newest?
