I plead guilty to whatever XY drift there is in the unrolling specification here, but a proper sailor in high seas will not abandon his complete mystification without reporting it as well as he can, for others with better perspective perchance to hear. It would seem files in the local::lib are not possessed of a,c, or mtime, whilst my crummy modules have all 3. My current best script follows with abridged output.

use strict;
use warnings;
use 5.014;
use File::Find;

my @directories_to_search = ( '.', 'C:\Users\Fred\Desktop' );
my @files;
find( \&wanted, @directories_to_search );
my @time = localtime;
say "local time is @time";

sub wanted {
   if ( $_ =~ m/.pm$/ ) {
      my $name    = $File::Find::name;
      my $success = max_acm($name);
      say "max_acm is $success";
      push( @files, $name );

   }
}

sub max_acm {
   use strict;
   use 5.014;
   use warnings;

   my $path = shift;
   say "$path is $path";
   my @array;
   push @array, 42;
   my $atime = ( stat $path )[8];
   if ( defined $atime ) { say "atime is ok"; push @array, $atime; }
   my $ctime = ( stat $path )[10];
   if ( defined $ctime ) { say "ctime is ok"; push @array, $ctime; }
   my $mtime = ( stat $path )[9];
   if ( defined $mtime ) { say "mtime is ok"; push @array, $mtime; }
   my $max = ( sort { $b <=> $a } @array )[0];
   return $max;
}

The times I'm looking for *in this context* are bounded below by when they become files in this locale. As further indication of XY shift, I would stipulate that it is sufficient to take the max of them, just in order to make useful time comparisons that will work for gilligan's island. I could just as well write a min function, compare it to the max, and have an interesting statistic about age, but first I'm trying to get squared away with the material in the exercises. I'm still *finding* modules, so I have to wonder how perl is interpreting the underlying windows platform. That neither a,c nor m time for the unix installed modules exists knocks my socks off and, along with the sea forward and backslashes, makes me believe that my logic is faulty.

Again, thanks for your comment.
