-These options disable the use of certain SSL or TLS protocols. By default
+This option disables the use of SSL version 3. By default
the initial handshake uses a method which should be compatible with all
servers and permit them to use SSL v3 or TLS as appropriate.

The timing program is not as rich in options to turn protocols on and off as
the L<s_client(1)> program and may not connect to all servers.

Unfortunately there are a lot of ancient and broken servers in use which
cannot handle this technique and will fail to connect. Some servers only
work if TLS is turned off with the B<-ssl3> option.
