Maybe you are right about this but I was just using the heading from darktable, to avoid confusion
This afternoon I made another test and found that on a Linux mint box the date is there. Yes, I used the same images as in my windows installation.
Right now I am pretty fed up with this so I’ll rest for a while.
Hm, that this happens on windows only makes me wonder if this is an exiv2 issue or exiv2 dependency/build issue. Are other information that would require exiv2 missing as well?
To chris and mica, I attach a printout of a typical ImageInformation. As far as I can see, it´s all there except the datetime.
To Claes, the idea has struck me!
Here is a printout from exiftool, I cut off a bit in the middle to make it a little smaller

I can fill in a couple of things, I have two separate Win 10 x64 computers and this is not working in any of them. But I have tested on Linux Mint and there it is OK.
This is not restricted to nef files, I have tested nef, rw2, jpg, tif and it all comes out the same.
To Claes: I use Win 10 x64 with Swedish language and the date/time is also set as Swedish 2019-12-12 and 09:04:12
I have also tested with Linux Mint and there it works fine, but, as Claes has showed, the datetime can be seen on windows installations also.
You are quite right, If I change the dateformat to English I can see the date!!! In the National settings I can even change the date to yyyy-mm-dd and it still works. What does not work is if I set the general format to Swedish.
Thank´s very much, this problem has been eating me for quite a while.
