Can’t center footer text – help!

This is driving me crazy I can’t seem to get my footer text centered on my site. Heres my footer code:

<div class="clear"></div>
		<div id="footer">
			<div class=center>&copy;<?php echo date("Y"); ?> <? bloginfo('name'); ?> - All rights reserved - Clemson University.</div>

		</div><!-- end footer -->

	</div><!-- end wrapper -->
</div>

	<?php wp_footer(); ?>
</body>
</html>

and here is my CSS code that I can find related to the footer:

#wrapper #footer {
width:960px;
height:20px;
border-top:1px solid #000000;
margin:0px;
line-height:20px;
text-align: center;
}

#wrapper #footer .left, #wrapper #footer .right {
float:center;
font-size:10px;
width:480px;
line-height:20px;
}

#wrapper #footer .right{
text-align:center;
}

#wrapper #footer .left a, #wrapper #footer .right a {
font-size:10px;
color:#666666;
text-decoration:none;
}

#wrapper #footer .left a:hover, #wrapper #footer .right a:hover {
color:#e0058c;
