Autorefreshing/no caching pages and Google

Can you put in html headers and not affect Google caching

I need to make sure that users get fresh copies of pages. Is there anything in the following script that would cause Google or other search engines to not cache their copy of my pages:

$now = gmdate('D, d M Y H:i:s') . ' GMT';
header('Expires: 0'); // rfc2616 - Section 14.21
header('Last-Modified: ' . $now);
header('Cache-Control: pre-check=0, post-check=0, max-age=0,no-store, no-cache, must-revalidate'); // HTTP/1.1
header('Pragma: no-cache'); // HTTP/1.0
header ("Expired: CONTENT=-1");

No. Perfectly legitimate.

However, I would also be sure to add the Google NOARCHIVE meta tag to all your html.
