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. .Sh SEE ALSO .Xr ssl 3 , .Xr SSL_CTX_set_timeout 3 , .Xr SSL_get_default_timeout 3 , .Xr SSL_get_session 3 , .Xr SSL_SESSION_has_ticket 3 , .Xr SSL_SESSION_new 3 .Sh HISTORY .Fn SSL_get_time , .Fn SSL_get_timeout , and .Fn SSL_set_timeout appeared in SSLeay 0.4 or earlier. .Fn SSL_set_time first appeared in SSLeay 0.5.2. .Fn SSL_SESSION_get_time , .Fn SSL_SESSION_set_time , .Fn SSL_SESSION_get_timeout , and .Fn SSL_SESSION_set_timeout first appeared in SSLeay 0.9.0. All these functions have been available since .Ox 2.4 .
