in reply to garbage at end of string in strptime

Apologies for the delay of code. My code is like 

my $last_executed =  $time_file . ".txt";
return 1 unless (-e $last_executed);

open(IN, '<' . $last_executed);
my $time = <IN>;
close(IN);

my $valid_time = $time;
return 1 if ( $valid_time !~ m/(\d{4})-(\d{2})-(\d{2})(?:T)?(\d{2}):(\
+d{2})/gi );

my ($year, $month, $day, $hour, $min) = $time =~ m#(\d{4})-(\d{2})-(\d
+{2})(?:T)?(\d{2}):(\d{2})#gi;
my $dt1 = DateTime->new ( year => $year, month => $month, day => $day,
+hour => $hour, minute => $min);
my $time2 = localtime->datetime;
my ($year2, $month2, $day2, $hour2, $min2) = $time2 =~ m#(\d{4})-(\d{2
+})-(\d{2})(?:T)?(\d{2}):(\d{2})#gi;
my $dt2 = DateTime->new ( year => $year2, month => $month2, day => $da
+y2,hour => $hour2, minute => $min2);

    What happened to Time::Piece:-). In general, it would be better to use a DateTime::Format::Strptime class like this: 
    #!/usr/bin/perl -l

use strict;
use warnings;
use DateTime::Format::Strptime qw();

my $format = DateTime::Format::Strptime->new(
    pattern   => '%Y-%m-%d %H:%M:%S',
    time_zone => 'local',
    on_error  => 'croak',
);

my $ts1 = '2012-02-15 00:00:00';
my $dt1 = $format->parse_datetime($ts1);
$dt1->add(
    hours  => 3, 
    minutes => 56, 
    seconds => 53,
);
print $format->format_datetime($dt1);

my $ts2 = '2012-02-15 00:00:00';;
my $dt2 = $format->parse_datetime($ts2);
$dt2->add(
    years   => 1,
    hours   => 4,
    minutes => 27,
    seconds => 25,
);
print $format->format_datetime($dt2);
