by using a small chunk of javascript.



check the system time, then either print ';good'; ...morning/afternoon/evening, dependent on the users time.



or if you want to change the page totally, in addiction to that.. use a URL redirect to another html file. eg..



if time %26gt; 9am %26lt;12 = url redirect ';m-index.html';

etc
