Dear Monks,
I try to iterate over the generated set of datetimes in the following way: 
#!/usr/bin/perl
use strict;
use warnings;

use DateTime;
use DateTime::Event::Recurrence;
use DateTime::Format::Strptime;

my $strp = DateTime::Format::Strptime->new(
    pattern => '%Y-%m-%d %T',
        );


my $datf = qq{2012-01-01 04:00:00};
my $datt = qq{2012-01-02 23:00:00};

my $start= $strp->parse_datetime($datf);
my $end = $strp->parse_datetime($datt);

my $day_set = DateTime::Event::Recurrence->hourly();

my $it = $day_set->iterator
                                (
    start  => $start->truncate(to=>"hour"),
    before => $end->truncate(to=>"hour"),
);

while ( my $dt = $it->next() )
{
    print $dt->datetime(), "\n";
}

This works.
What I need however is to generate only the hours between 07:00:00 and 22:00 :00.
I tried 
my $day_set = DateTime::Event::Recurrence->hourly(
     hours => [7, 22], 
);

but this brings an error message "invalid argument 'hours' " - apparently one can use only the next low time step since it works with minutes=>[10, 30] for example.
I have not much experience with Datetime modules yet.
Please give me a hint.
Thanks in advance.
