Returns the timeout limit of <code>SSLSession</code> objects grouped
under this <code>SSLSessionContext</code>.
<p>
If the timeout limit is set to 't' seconds, a session exceeds the
timeout limit 't' seconds after its creation time.
When the timeout limit is exceeded for a session, the
<code>SSLSession</code> object is invalidated and future connections
cannot resume or rejoin the session.
A check for sessions exceeding the timeout limit is made immediately
whenever the timeout limit is changed for this
<code>SSLSessionContext</code>.
@return the session timeout limit in seconds; zero means there is no
limit.
