$ su another_user
$ touch -d 'now' file # works
$ touch -d 'yesterday' file # fails
touch: setting times of ‘file’: Operation not permitted
I see no description of that in the documentation, and it just seems wrong. If other users have full control over the file (and surrounding directory), shouldn't they be able to change its date?
The same behavior is seen with `touch -t`.
Best,
