It is a feature. You can enable timestamp update in the configuration 
dialogue (metadata) and there in the first tab (Verhalten in german).

The image editor (showfoto) is different. If you hit save, the whole 
image is written to the hard disk. In main digikam only the metadata 
is updated. The image data is untouched.
