Hi Uwe,

TL DR; I add the timestamp automatically on entry creation as a hook 
[2], in fact, I have several hooks on entry creation and I think is a 
good way to handle this. I am happy with my setup since I started using 
it in 2023.

Let me share my experience on that topic (and very happy to hear other 
experiences and/or feedback), I hope the offtopic inside is welcome and 
useful:

1. Before, I was manually adding timestamp headers as a postfix for the 
creation of the header (and this is how I reverted using this script per 
target buffer [1]) to transform to CREATED properties (see here the 
automation on how I add the timestamp automatically on entry creation 
[2]), which I think are even better, specially, because then you can add 
that column to your table-reports such as clocktable, org-ql, propview, 
custom org-map-entries stuff.
2. After, as a prefix, in the journal files, for facilitating 
alphanumeric sorting of items in my customized journal (with a structure 
of year > week > day). I finally got rid of that, and brain and eyes 
appreciated that movement, it is too much noise to see a lot of items 
with timestamp. I discovered that problem when I started using 
variable-pitch mode, which with modes themes works very nice with 
(enable variable: (setq modus-themes-mixed-fonts t) ). Then, 
alternatively, sorting can be done by adding "SCHEDULED" to all items 
created on certain buffers and levels [3], which I also add for certain 
org-agenda files (then I use schedule as a poor's man alternative to 
anki [4] for space repetition [5], which could of course involve real 
tasks and projects apart from the typical usecase of memorizing concepts).

I do it this way and it works fine for me since that date I use it:

Cheers,
pinmacs
