I am trying to get the timestamp of files from a directory

  #!/usr/bin/perl
use strict;
use warnings;
#use Nexius::CM::Utils;
#use Getopt::Long;
#use Data::Dumper;
#use Switch;
use File::stat;
use Time::localtime;
use POSIX;


#use Time::localtime;
#$tm = localtime;

my $file1 =shift;

opendir(DIR,"./tmp");
my  @dir1=grep { !/^\.+$/ } readdir(DIR);
closedir(DIR);
#$file_count = 0;

 my $date1=0;
foreach $file1 (@dir1)
{

  my $latest = POSIX::strftime("%Y%m%d",
                                localtime( ( stat $file1 )[9] )
                                );
                $date1 = $latest if($latest && $date1 < $latest);
   $date1 =~ /(\d\d\d\d)(\d\d)(\d\d)/;
        print "Latest update for Nortel GSM is: $2/$3/$1\n";

}
