<?php
// Include the caching library:
require_once '09c06-1.php';
//require_once 'cache.php';

// Initialize the caching:
cache_page();

// Now let's just echo out the date.  If caching works, when you
// reload this page, the date will not change until an hour has passed:
date_default_timezone_set('America/New_York');
echo date(DATE_RSS, time());
?>
