- Download dc0a73e8e6.jpg (as provided by Karl02) to a temporary folder near you.
- Start XnView and navigate to that folder.
- Go to Tools » Options...:
- [ ] Keep date/time for saving (General » File Operations)
[ ] Keep original date/time attributes (Browser » Misc. » Rotation)
[x] Use Embedded thumbnail (Browser » Thumbnails » Appearance)
- [ ] Keep date/time for saving (General » File Operations)
- Select the thumbnail of dc0a73e8e6.jpg and go to Tools » JPEG Lossless transformations » Flip Vertical:
The image and its embedded EXIF thumbnail are updated, but the date/time stamp stays the same.
- Open dc0a73e8e6.jpg and go to Edit » Set Selection size » 8x6.
- Then go to Tools » JPEG Lossless transformations » Crop.
- Back in Browser mode, you'll notice that the date/time stamp has been updated, but not the embedded EXIF thumbnail.
- Select the thumbnail and go to Edit » Metadata » Recreate EXIF thumbnail.
If you try to open dc0a73e8e6.jpg again, you'll notice that it is kaput.

The results of my tests with v1.94.1:
- Browser mode: Tools » JPEG Lossless transformations
Rotate 90° left
Rotate 90° right
Rotate 180°
Rotate based on EXIF value
Flip Vertical
Flip Horizontal
Rotate 90° left
Rotate 90° right
Rotate 180°

User settings are respected = Date/time stamp is updated
User settings are not respected = Date/time stamp is not updated
