Try this, you have to use POSIX, but ...
use POSIX qw/difftime mktime/;
my $now = time();
my @then = ($ARGV[0] =~ /^(\d{4})(\d{2})(\d{2})/);
my $then = mktime(0,0,0,$then[2],$then[1]-1,$then[0]-1900);
my $diff = difftime($now,$then);
printf("%d days", int($diff/86400) );
printf(", %d hours", int( $diff%86400)/3600 );
printf(", %d minutes ", int( ($diff%86400)%3600 )/60 );
printf(", %d seconds \n", ( ($diff%86400)%3600 )%60 );
It may not be elegant, and could defintely benefit from some cleaner formatting like use of constants, but it gets the point across
