The timeout you pass to Net::LDAP::new() is passed directly to the socket
constructor (perldoc IO::Socket).

As far as I can tell, it is used in connect() and accept() and it is
measured in seconds (it is passed to alarm()). As these two calls can take
up to 5 minutes to fail because of TCP timers, having a timeout shorter
than this can be desirable. Connect() is used by clients when creating the
connection to the server, accept() is used by servers.

To provoke the 5 minute failure, you have to try to connect to an IP
address of a machine outside of your subnet which doesn't exist. I've seen
Linux do some funny things in this area, whereas Solaris for example
behaves as expected.
