recording time export darktable

Software darktable
1

Hello everyone,

I’ve recently started editing my RAW images with darktable and I’m very happy with the software.
But when I export my images as JPEGs, the EXIF data of the JPEG file always contains the export time instead of the capture time. This bothers me, but I don’t know how to change it.
Under “export” → “preferences…” I have marked “EXIF Data”.

Perhaps you know how I can change this.

I look forward to your answers!

Best regards
Noah

If I look with exiftool at an image exported with darktable, I see (among others):
“Date and Time” this corresponds to the creation date of the jpg
“Date and Time Original”,
"Date and Time (digitised),
"Date and Time (original): the last three all correspond to the time the original image was captured.
I also see three file-related dates, which depend on the file-system (they are not part of the embedded metadata).

So it looks like your viewer reports the date the jpg was created (not unreasonable in itself)

Nothing missing in jpg, even additional entry as [xmp].
