ssl_session_timeout issues

[Nomad Worker]

I read the code of ssl module, the directive ssl_session_timeout seems only
used for ssl session cache, not for ssl session ticket.  
the document describes the directive as 'Specifies a time during which a
client may reuse the session parameters.' Is it not exactly?
Is there any timeout for ssl session ticket ?
