How to know a HTTPS connection in use is TLS-based or SSL-based?

If I want to use TLS instead of SSL in Apache2, is there anything special to config?

Does it matter? TLS can be considered just a newer version of SSL, and SSLv3 is still secure and used.

"HTTPS" doesn't imply any version. By default, Apache's mod_ssl accepts all protocol versions, and most clients pick the newest supported one. You can change it using the SSLProtocol directive - most recent browsers support at least TLS v1.0.

(It would be helpful if you updated your question with why do you want TLS in particular.)
