Not sure if this is a failure of documentation or a bug, but it is worth noting that this function seems to return the timestamp of the script execution by default, not the current time. So e.g. this:

<?php

echo http_date();
sleep(60);
echo
http_date();

?>

will output the exact same string twice.
