Documentation for routine changed

Documentation for routine changed, assembled from the following types:

class IO::Path

From IO::Path

(IO::Path) method changed

Return an Instant object representing the timestamp when the inode was last changed.

"path/to/file".IO.changed;                    # e.g. Instant:1424089165 

To obtain a human-readable form of the timestamp, use a DateTime object:

say DateTime.new("path/to/file".IO.changed);  # e.g. 2015-02-16T12:18:50Z 

or more readably:

my $change_instant = "path/to/file".IO.changed;
my $change_time = DateTime.new($change_instant);
say $change_time;                             # e.g. 2015-02-16T12:18:50Z 

role IO::Special

From IO::Special

(IO::Special) method changed

method changed(IO::Special:D: --> Instant)

The last changed time always returns an undefined Instant
