@kaia @4censord it depends how you change it.

An "atomic write" to a file will write out the new content to a temporary file, delete the old file, and move/rename the temporary file to the old file path.

This would always cause a file to have a mod and create time to be the same.

If you're editing with any text editor or flat-file database, they all do this since it prevents data loss if the write fails.
