This program is pretty much the equivalent of the 'C' hello world program:

Put this in your cgi-bin directory as "time.cgi".
this may under a directory like: public_html

Change the permissions so that anybody can read it or execute it.
chmod a+rx cgi-bin/time.cgi

Then you just have to tell folks the URL, maybe:
http:your_machine/~yourName/time.cgi
The user clicks on that link and the program runs.
In this case it just sends an html page with the current time.

Try it!

#!/usr/bin/perl -w

use strict;
use CGI;

my $q = new CGI;
my $timestamp = localtime;

print $q->header ("text/html"),
      $q->start_html ( -title => "Current Time"),
      $q->h2 ("Current Time"),
      $q->hr,
      $q->p( "This system figures current time as: ",
             $q->b($timestamp)
            ),
      $q->end_html;

In this case, the code is inefficient because among other things, there is a huge overhead in the object method calls.

But under a normal ~Unix system where you are allowed to have a cgi-bin directory, this is "hello world".

Get this working and we go from there.
With performance issues and blah,de,blah,de,blah.
