Then edit /templates/products_more.tpl (or whichever relevant template for where you want the date to appear) and put
$config[sTodaysDate]
where you want the date to be displayed.
If you want other HTML around it, either put it in the template or in the config variable itself. You can take the 'Todays Date: ' text out of the config variable and put it in the template instead if you wish (or change or remove it entirely. You can change the date format (visit the link supplied by sadman above). Note: this puts todays date on the More Info page for every product.
