Two thoughts on this:
- you say it's the filesystem timestamp that's changed. Afaik, that's not 
under Digikam's control. (I suspect that the configuration option refers to 
dk's database).

- changing a tag which is stored in the file *would* change the file contents, 
so it's normal that the filesystem date/time is changed: it normally reflects 
the last change to the contents of the file, and the filesystem has no 
knowledge of the file's contents.
If, otoh, the tag is *not* stored in the file, the file system timestamp 
should remain the same.
