+.Sh DESCRIPTION
+.Fn SSL_SESSION_get_time
+returns the time at which the session
+.Fa s
+was established.
+The time is given in seconds since the Epoch and therefore compatible to the
+time delivered by the
+.Xr time 3
+call.
+.Pp
+.Fn SSL_SESSION_set_time
+replaces the creation time of the session
+.Fa s
+with
+the chosen value
+.Fa tm .
+.Pp
+.Fn SSL_SESSION_get_timeout
+returns the timeout value set for session
+.Fa s
+in seconds.
+.Pp
+.Fn SSL_SESSION_set_timeout
+sets the timeout value for session
+.Fa s
+in seconds to
+.Fa tm .
+.Pp
+The
+.Fn SSL_get_time ,
+.Fn SSL_set_time ,
+.Fn SSL_get_timeout ,
+and
+.Fn SSL_set_timeout
+functions are synonyms for the
+.Fn SSL_SESSION_*
+counterparts.
+.Pp
+Sessions are expired by examining the creation time and the timeout value.
+Both are set at creation time of the session to the actual time and the default
+timeout value at creation, respectively, as set by
+.Xr SSL_CTX_set_timeout 3 .
+Using these functions it is possible to extend or shorten the lifetime of the
+session.
+.Sh RETURN VALUES
+.Fn SSL_SESSION_get_time
+and
+.Fn SSL_SESSION_get_timeout
+return the currently valid values.
+.Pp
+.Fn SSL_SESSION_set_time
+and
+.Fn SSL_SESSION_set_timeout
+return 1 on success.
+.Pp
+If any of the function is passed the
+.Dv NULL
+pointer for the session
+.Fa s ,
+0 is returned.
