Hi

wrote a little script to adapt subtitles timings in .srt files, but am getting bitten by a strange extra second when using a negative offset 

use strict;
use warnings;
use Data::Dump qw/pp dd/;
use DateTime;
use DateTime::Duration;

my $dur = DateTime::Duration->new(
    hours       => 0,
    minutes     => 0,
    seconds     => -1,
    nanoseconds => "000000000",
);

warn "dur:\t", pp
    $dur->in_units(
        qw/hours minutes seconds nanoseconds/
    );

exit;

dur:    (0, 0, -1, -1000000000) at d:/tmp/t_datetime.pl line 14.

it seems that nanoseconds are getting wrong, not sure if I misunderstood the docs for DateTime::Duration ...

This problem disappears if nanoseconds are missing or set to something else than 0, hence I do have an easy workaround.
