After testing a few alternatives, it seems to be that the issue is with DateTime::Set->from_recurrence. Manually populating a set seems to work.
</#!/usr/bin/perl -w
use strict;
use diagnostics;
use DateTime;
use DateTime::Set;
my $date = DateTime->today();
my $date2 = $date->clone();
$date2->add('days' => 14 );
my $set1 = DateTime::Set->from_datetimes( dates => [ $date, $date2 ]);
my $iter = $set1->iterator;
while( my $d = $iter->next ) {
print $d->datetime, "\n";
}
my $date3 = $date->clone();
$date3->add('days' => 7);
print $set1->contains( $date3 ),"\n"; # gives 0 correct!
my $biweekly = DateTime::Set->from_recurrence(
'recurrence' => sub {
return $_[0]->truncate('to' => 'day')->add('days' => 1
+4)
},
'after' => $date
);
my $set4 = DateTime::Set->from_datetimes( dates => [ $date3 ] );
print $biweekly->contains( $set4 ), "\n"; # gives 1 wrong!
print $set4->contains( $biweekly ), "\n"; # gives a warning
You said you had a solution already, but you could create the recurring dates yourself and then it should (hopefully) work.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
