The error message is telling you exactly what the error is: you have an extra 2 that it can't format. For example, an example with garbage 2:

#!/usr/bin/perl -l

use strict;
use warnings;
use Time::Piece;

my $time = Time::Piece->strptime(
    "2013-02-15 19:07:292", 
    "%Y-%m-%d %H:%M:%S");
print $time;

Now without the extra 2:

#!/usr/bin/perl -l

use strict;
use warnings;
use Time::Piece;

my $time = Time::Piece->strptime(
    "2013-02-15 19:07:29", 
    "%Y-%m-%d %H:%M:%S");
print $time;

Does that help? If not, please post your code, and we'll go from there.
