org-time-stamp-custom-formats with out the name of the day of the week

[Uwe Brauer]

Hi 

I have set
  (setq org-time-stamp-custom-formats '(" %d.%m.%Y " . " %d.%m.%Y"))

Now a time-stamp gets displayed (german convention) 


<31.08.2022>  

However when I run 

 org-toggle-time-stamp-overlays


I see <2022-08-21 Mi>

Which is well expected. So I am wondering, is there a way truly to have 

<31.08.2022>   interpreted as a org time-stamp?

Regards

Uwe Brauer

Timestamp format is hard-coded in Org syntax. See

I see, but I just learned that also 

<2022-09-01>

Is interpreted as a timestamp not only 

<2022-09-01 Thu>


However although I have set

  (setq org-time-stamp-custom-formats '(" %d.%m.%Y " . " %d.%m.%Y")

The day of the week gets always inserted.

That is a bit inconsistent I would say.

Yes. Day name is optional.

I am not sure what you are referring to.
org-time-stamp-custom-formats is not changing the actual text. Just the
way timestamps are displayed when org-display-custom-times is non-nil.

I see, the question simply is this:

How can I achieve that org-time-stamp inserts the date *without* the day
name?!

This cannot currently be customized. However, you can change
org-time-stamp-formats constant. Removing the %a should be safe.

FWIW, I have this in an (eval-after-load 'org ...)

  (setq org-time-stamp-formats
     '("<%Y-%m-%d>" ."<%Y-%m-%d %H:%M>"))

since years (> 5) and haven't observed any side effects. But then
I don't meet every nook and cranny of org (I bow in awe to those
who meet half of them :-)

This only works because you changed org-time-stamp-formats in one of the
few safe ways.

Org declares org-time-stamp-formats and Org code treats its value as a
constant making various kinds of unsafe assumptions that can break
things if the value of org-time-stamp-formats is changed. For example,
it is assumed that first/last characters are triangular brackets; it is
assumed that the output can be parsed using parse-time-string; it is
assumed that 1..11 substring in the format contains a full date; it is
assumed that the formatted output conforms to timestamp syntax; etc.
