Just for grins, you could use something like this. Time::Local is a core module that translates a string representation of time into seconds - think of it as a reverse of localtime.
#!/usr/bin/perl -w
use strict;
use Time::Local;
my $start = "7:30";
my $end = "11:45";
my $interval = 15;
# Assuming time is in a 24-hour format and adjusting for my timezone :
+)
my ($start_sec,$end_sec) = map { /(\d+):(\d+)/;timelocal( 0, $2, $1, 1
+, 1,1970 ) } $start, $end;
# In case the times cross the midnight boundary
$end_sec += 86400 if ( $start_sec > $end_sec );
my $int_sec = $interval * 60;
while ( $start_sec <= $end_sec ) {
printf "%d:%02d\n", (localtime($start_sec))[2,1];
$start_sec += $int_sec;
}
I use timelocal to translate the given times into the correct seconds - including timezone adjustments. I chose the Epoch for no particular reason. After that, I simply let localtime do its thing.

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).
