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);
