JPGs are missing EXIF data

[locuturus]

Describe the bug
JPGs lack the date/time original field. To be fair they do contain the modify date field in EXIF but I worry this might not be handled consistently across gallery apps on different platforms.

To Reproduce
Take a photo, saving both jpg and dng.

Expected behavior
I expect both photos to contain typical EXIF data, in particular I care about the date/time field.
