Thank you LanX and Anon. I thought meta refresh was a blunt approach. I also figured Mojo might provide an HTTP solution using NPH or something like the venerable CGI::Simple (websockets I guess). Anyway I figured out how to do the job, but will research your other suggestions for a more elegant solution:
#!/usr/bin/perl
use strict;
use warnings;
use Mojolicious::Lite;
use Time::HiRes 'time';
get '/' => sub {
my $c = shift;
$c->clock;
$c->render('index')
};
helper clock => sub {
my $c = shift;
$c->stash(clock => time)
};
app->start;

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).

or How to display code and escape characters
are good places to start.
