The sort by date option in Gwenview - and to the best of my understanding the
only thing it can do when it wants to sort by the file manager's "date" sorting
- is to sort by the file system's "modified date". Nothing else makes much
sense - IMHO.

This new commit -
https://invent.kde.org/graphics/gwenview/-/commit/6545c47de9fdf830739737c52cbeaa2ce6a6411c
- adds metadata fields for "created date" and "accessed date" - which, in my
opinion, only exemplifies how much these fields are useless and serve only to
confuse and do not add much information:
* "accessed date" is always "now", because you just accessed the file to show
it in gwenview (or thumbnail it or anything). "accessed date" is pretty much
useless unless you have some non-interactive process that only scans directory
listing.
* "created date" is the time the file was physically created on the file system
- which can be newer than "modified date" (for example when copying the file
from another storage medium), or can be unset (some file systems don't have
that feature).
* "exif date" is optional and a lot of images do not have it - or even being
able to store it, so sorting by that is going to be hit and miss (and that is a
lot of miss). A good image importer might set the file info modified date
according to the EXIF data, which is what I actually expect from all digital
cameras and everything that generates EXIF date fields.
