First, when you set the expiration date, that information is sent to the
browser, but not returned when the browser sends the cookie back to the
server. It's only used by the browser to determine when it should get rid of
the cookie. So, you won't see that information anywhere in your CF
variables, using CFDUMP.
Second, when you set a cookie, the browser sees something like this:
Set-Cookie: CFID=251232; expires=Sun, 27-Sep-2037 00:00:00 GMT;
path=/;
This HTTP header contains all the information for the cookie, including the
expiration date. When you use EXPIRES="NEVER", as in the above example, the
cookie is actually set to expire in the relatively distant future, many
years from now.
Now, when I used CFCOOKIE like so:
<cfcookie name="foo" value="bar" expires="2/27/2002">
it generated this:
Set-Cookie: FOO=bar;expires=Wed, 27-Feb-2002 22:22:05 GMT;path=/
You might find it useful to look at these HTTP headers. One easy way to do
that is with HTTP Analyzer:

You may also want to play around with different date formats; I seem to
recall just generating a valid GMT date myself in the past, and using that,
but it's been a while.
Finally, if you want the cookie to expire in 30 days, why not just say so?
<cfcookie name="foo" value="bar" expires="30">
