Which, in practice, tends to mean "the file has been changed in n days,
or the file has been renamed in n days, or a link to the file has been
added or removed in n days, or the permissions have been changed in n
days, or the owner has been changed in n days, or...." Basically, either
the file itself has been changed, or any of the changable attributes
that "stat" returns, with the possible exception of the accessed time,
has been changed.
