You can use openssl ca that allows to set arbitrary start date to
generate selfsigned certs as well (-selfsign option).

That seems to require some stuff I don't have installed:

warthog>openssl ca -in signing_key.priv -extensions v3_ca -out newcert.pem
Using configuration from /etc/pki/tls/openssl.cnf

(the /etc/pki/CA/private/ dir is inaccessible if not root and doesn't in any
case contain cakey.pem).

Do I need to start with all the CA stuff in the right places to use it?

You can configure it to point to a different directories. But yes, you
have to create a CA cert and so on.
