Seeking an example of Time::Period usage

[jking]

My first post on pm. I've read all the docs and asked about documentation on Time::Period in the cb; I've googled and experimented... I still need a little bit of help. I'm trying to create a script that iterates over a time period and prints out a start and end time for each day in the range. The end result will hopefully be a textfile that resembles something like this:

2006-09-22 9:22am - 6:45pm
2006-09-25 9:20am - 6:15pm

In the following script, $return always returns -1. In the Time::Period pod, this means that inPeriod() is not getting a properly formed value as it's input. Here's my code:

#!/usr/bin/perl -w

use strict;

use DateTime;
use DateTime::Span;
use DateTime::Set;
use Time::Period;

my $start_date = DateTime->new( year => 2006,
                                month => 9,
                                day => 10,
                                hour => 9 );

my $end_date = DateTime->new( year => 2006,
                              month => 12,
                              day => 20,
                              hour => 18 );

my $span = DateTime::Span->from_datetimes( start => $start_date, end =
+> $end_date );

my $days = DateTime::Set->from_recurrence
  (
            span => $span,
            recurrence => sub {
              return $_[0]->truncate( to => 'day' )->add( days => 1 )
            },
  );

my $iter = $days->iterator;
while (my $dt = $iter->next) {
  my $result = inPeriod( $dt->datetime, "wd {Mon-Fri}" );
  if ($result) {
    printf("TRUE: %s -- \$result: %d\n", $dt->ymd, $result);
  }
}
