The following will cause a browser to refresh the page every 30

  if ($action == 'browse') 
    $HTMLHeaderFmt['refresh'] = 
      "<meta http-equiv='Refresh' Content='30; URL={\$PageUrl}' />";

It can be done sitewide in local/config.php (probably not recommended),
or in a per-page or per-group customization file.

Or, one could use the following customization to add a '?refresh=nn'
option to all pages:

  if (@$_GET['refresh']) {
    $r = $_GET['refresh'];
    $HTMLHeaderFmt['refresh'] =
      "<meta http-equiv='Refresh' Content='$r; URL={\$PageUrl}?refresh=$r' />";

For demonstration, I've enabled this latter option at
http://www.pmwiki.org/wiki/Test/Refresh .
