Question

convert datetime format yyyy-mm-dd hh:mm:ss (Might be a string) into UTC,
Looking into DateTime but I don’t see how to parse the string?

UPDATE:

Is this working correctly?

require 5.002;

use strict;
use warnings;

use DateTime::Format::DateManip;

my $string = '2010-02-28 00:00:00';

my @dates = (
    $string
);

for my $date ( @dates ) {
    my $dt = DateTime::Format::DateManip->parse_datetime( $date );
    die "Cannot parse date $date, Please use a valid date in this format 'yyyy-mm-dd mm:hh:ss'"  unless defined $dt;
    print $dt."\n";
    $dt->set_time_zone( 'UTC' );
    print $dt."Z\n"; # Is this correct???
}

Have a look at this SO question, How can I validate dates in Perl? for one answer.

There are also some nice DateTime helper modules on CPAN. For eg. DateTimeX::Easy which allows you to create DateTime objects like so:

use DateTimeX::Easy;

my $a_date    = DateTimeX::Easy->new( '11/17/2008 12:01am' );

my $tomorrow  = DateTimeX::Easy->new( 'tomorrow' );

my $last_week = DateTimeX::Easy->new( 'last week' );
