Hi
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!
Hi
Sorry about the mess!
Yes, I see that. I was asking about the output of that tag from exiftool, not darktable.
Perhaps you can post a problematic raw file as well.
Hi Mica
Here is a printout from exiftool, I cut off a bit in the middle to make it a little smaller

Hej Börje!
Yes, your upload works fine.
Here is how darktable 3.0.0rc1 reports the date on my Win 10/64b:
Mvh
Claes i Lund
Hi not works you .nef in Win7x64 and DT 3.0.0rc2.
I have the same problem with a Pentax and Windows OS:
In.xmp the Datetime is correct but in Lighttable not.
Hi
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.
Greetings
Börje
Hej Börje!
What are your what’s-it-called… language/date/number settings?
Have fun!
Claes in Lund, Sweden
I am running on Linux Mint 19.2 - Cinnamon 64 bit, with DT version 2.6.3 and the date shows just fine for me Bjo after downloading your photo.
The image creation date is visible using darktable 2.6.2 under Linux (Kubuntu 18.04), so it seems to be a MS-Windows issue.
Hi
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.
Greetings
Börje
God morgon, Börje,
I wonder if Win & Swedish settings might be the culprit,
since I use UK settings (and it works here).
Mvh
Claes i Lund
God förmiddag Claes
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.
Greetings
Börje

Hi, could you explain it a little more or put some screenshots.
I can’t replicate it.
Thanks!!
@git But you are not on Win X, right?
What are your Language/National Settings, especially Date?
Have fun!
Claes in Lund, Sweden
Hi Git and Claes
Here you can see screenshots of my settings.
First of all I still use Swedish as overall language.
But when I come to the regional settings I use English but with a little tweak on the dateformat to have it Swedish.
The resulting darktable datetime looks like this, funny thing here is that the dateformat is as if it was English but this is only in darktable as far as I can see. For example the date in the systemclock down to the right is in Swedish. For me, I can live with this.
Greetings
Börje
Fabulous!!! now if it works fine: 
the key is in the regional language.
and the clock:
It is not the local language OS, but DK does and works well.
Test in Win7x64 Pro.
I add it to the open issue
Thanks.

Hi, with latest release 3.0.0 final i return to regional language and Datetime are good. You can check it?
Thanks.
Hi
I tested this and this is really weird. I switched back to Swedish regionformat and darktable displays days in Spanish(!!?), lun, mar, jue, vie, and dom ( Monday Tuesday Thursday Friday and Sunday) but Wednesday and Saturday does not show anything, just a hyphen. There is nothing in my windows settings that has anything to do with Spanish.
Funny with computers is´nt it 
The images are taken the 12:th and 13:th of may.
Greetings
Börje
