.Pp
|
|
If
|
|
.Fa times
|
|
is
|
|
.Pf non- Dv NULL ,

The access time is set to the value of the first element, and the
|
|
modification time is set to the value of the second element.
|
|
The caller must be the owner of the file or be the super-user.
|
|
.Pp
|
|
In either case, the inode-change-time of the file is set to the current
|
|
time.
