Hi,
ox-odt.el ignores `org-export-date-timestamp-format'.
Instead, it uses a variable `org-odt-use-date-fields', which maps
/all/ dates to the styles "OrgDate1" and "OrgDate2". I'm not sure if
these are meant to be customizable or not. In LO I'm able to change
the style by clicking on the timestamp so probably the style has to be
specified that way, somehow.
Unfortunately, the undocumented `org-odt--format-timestamp' does not
seem to support alternative formats, but again, this may be due to
fact that dates are formatted in LO.
I /might/ have time to look at this myself over the weekend, unless
someone knows how to fix it.

No, judging by the manual entry, it was intended for customizing the
appearance of timestamps in the buffer, which it does, see below. To
accommodate people who think ISO time format is just too darned
/sensible/...
But it has the nice (and little-mentioned) side effect that you can use
it to change the appearance of timestamps in exports, where
non-geeky-looking everyday-language dates are often comme il faut. Works
nicely in HTML, for instance, except that you still get geeky-looking
brackets around the dates (may need a filter to remove those).
It's nice, for instance, if you have a document with a lot of dates in a
European format and need to switch to an American format; you can do it
by changing a setting.
And the ODT exporter builds on this to give date fields that can be
further changed in LibreOffice.

I don't know about "recommended". It doesn't seem to be documented for
export at all. And as for ODT, the code comments say the feature
translating from custom time stamp formats to ODT date styles is
"experimental". Seems to work OK, though.

In Org, or in LibreOffice once you set the language there? If the
#+LANGUAGE keyword is supposed to affect date formatting in Org output,
I must be missing a trick.

Not anytime soon, I'm afraid; pressed for time.
Yours,

O-o-okay.

While I really want this functionality, I think that this way of using
it is a bug. It should depend on a separate org-export-· variable. ..

Wait, so does this variable change how dates are interpreted or not?
I.e. can I "choose" whether <2010-01-10> is January 10th or October
first? Or is an Org timestamp always in sensible ISO?

Right.

I like the possibility, but I think export and buffer display should be
separated.

In LO some of the date formatting is a function of the document
language. The document language (or maybe region language, I don't
really know...) is seen at the bottom.
Date has a gray background indicating it's special... With sufficient
time and creativity you can get to a menu for formatting the date. Some
of these formats (especially the "human-friendly" ones) will depend on
the language.
On the other hand, "Table of Contents" seems completely independent of
the document language. . .

I think #+DATE might not be truly affected by #+LANGUAGE, after all, but
rather be affected of different system languages on my two home-PC and
work-PC (I'm unable to get this computer—which has English as a system
language—to export dates in other languages via
org-export-date-timestamp-format).
This is probably a separate bug.

That's fine. I will try to look into this; hopefully soon.
