[R] Does file.info man page describe ctime corrrectly?

(R 2.8.0 on Debian GNU/Linux sid)
mtime, ctime, atime: integer of class '"POSIXct"': file modification,
creation and last access times.
This implies that ctime is "file [...] creation [...] time"
Has R implemented ctime differently to Unix?
I understand, on Linux at least, that ctime is the last change time
(not the creation time). See "man ls" which says:
-c [...] ctime (time of last modification of file status
However, testing seems to indicate file.info is returning the change
time, not creation time (I'm not sure we can actually determine
creation time of a file on Linux).
Perhaps just a file.info documentation slip?
