[O] org-time-stamp in latex buffer

[Uwe Brauer]

Hi

I changed by org-time-stamp-custom-formats
to 



org-time-stamp-custom-formats is a variable defined in ‘org.el’.
Its value is ("«%d-%m-%Y %a»" . "«%d-%m-%Y %a %H:%M»")
Original value was 
("<%m/%d/%y %a>" . "<%m/%d/%y %a %H:%M>")


And indeed in an org buffer this format is used. However when I try to
use org-time-stamp in a latex buffer the string
<2017-07-28 Fr>
is inserted which does not respect my new setting.

What is wrong?

Thanks
