L~R, thanks for the full framework! I was headed down the same path and manipulated the examples from the Panther to work with 24 hours per day:
#!/usr/bin/perl -w
use strict;
my %base_hours = ( sun => 0, mon => 24, tue => 48, wed => 72 , thu =>
+96, fri => 120, sat => 144 );
my $vector = interval_parse("Sat 9-17, Sun 9-17");
my $bits = unpack("b*", $vector);
print $bits, "\n";
sub interval_parse {
my ($interval_sequence) = @_;
my ($time_range) = "";
foreach my $day_hours (split /,/, $interval_sequence) {
my ($day, $from, $to) = ($day_hours =~ /([A-Za-z]+).*(\d+)-(\d+
+)/);
my $base = $base_hours{lc $day};
$from += $base;
$to += $base;
for (my $i = $from; $i < $to; $i++) {
vec($time_range, $i, 1) = 1;
}
}
return($time_range);
}
Thanks for the pointer!

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).
