Adding categories messes with create date

[orbspider]

It appears that the exif and create date are getting altered by adding categories.

1. add category to files
2. sort by create date,
->files move to end of list.
3. properties > create date (is changed to today's)

Earlier I found that adding a category and sort by exif date,
->files move to top of list
but the exif date is not altered. However I can't reproduce it right now!

I don't think the create date should be effected by adding categories, right?

EXIF date is not modified, for created date, settings>General>File operations>Embedded metadata is checked?

[orbspider]

Yes it is checked.

[xnview]

Yes it is checked.

are you able to reproduce it?

[orbspider]

Oui, je peux.

1. copy files to a new folder
2. select sort by Create date
3. select 1st file
4. add a category and apply it
5. press F5
6. file jumps to end of list
7. Open Info pane - Creation date/time: it has changed to today's

ok, right. Currently on linux i don't know how to change the creation date/time

On Unix there is no such thing as "creation time". There are 3 time values :
- ctime: last time file metadata (name, time, attributes, ACL, ...) was modified
- atime: last time the file content was accessed
- mtime: last time the file content was modified

"ctime" is frequently wrongly documented, including in several Unix variants man pages.
