Is the server modified date updated with permission changes?

[Hans-Peter]

Pretty much just the title.

When I get the file metadata (with files/get_metadata or files/list_folder), I get a server_modified, which seems to be just a more sensitive variant of the client_modified timestamp (so client_modified only changes when the content of the file changed while server_modified changes with moves, renames etc.), but does the server modified timestamp also update on permission changes? Because I used to think it does, but I'm currently testing it and it infact doesn't seem to be the case? Is this normal and was it always this way?

Hello,

Files moves and renames are update the `server_modified` property because they are making changes to the file. Changes to permission are not considered direct changes to the file so the field doesn't get updated. 

To my knowledge, behavior has not been recently changed.

One small caveat: some permission changes, like sharing a folder that contains the file, will actually move (or otherwise modify) the file under-the-hood which cause an update to `server_modified` on that file.
