The time is given in seconds since the Epoch and therefore compatible to the time delivered by the \fBtime()\fR call. .PP \&\fBSSL_SESSION_set_time_ex()\fR replaces the creation time of the session \fBs\fR with the chosen value \fBtm\fR. .PP \&\fBSSL_SESSION_get_timeout()\fR returns the timeout value set for session \fBs\fR in seconds. .PP \&\fBSSL_SESSION_set_timeout()\fR sets the timeout value for session \fBs\fR in seconds to \fBtm\fR. .PP \&\fBSSL_SESSION_get_time()\fR and \fBSSL_SESSION_set_time()\fR functions use the long datatype instead of time_t and are therefore deprecated due to not being Y2038\-safe on 32 bit systems. Note that such systems still need to be configured to use 64 bit time_t to be able to avoid overflow in system time. .PP The \fBSSL_get_time()\fR, \fBSSL_set_time()\fR, \fBSSL_get_timeout()\fR, and \fBSSL_set_timeout()\fR functions are synonyms for the SSL_SESSION_*() counterparts. .SH NOTES .IX Header "NOTES" 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 \&\fBSSL_CTX_set_timeout\fR\|(3). Using these functions it is possible to extend or shorten the lifetime of the session. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBSSL_SESSION_get_time_ex()\fR and \fBSSL_SESSION_get_timeout()\fR return the currently valid values. .PP \&\fBSSL_SESSION_set_time_ex()\fR returns time on success. .PP \&\fBSSL_SESSION_set_timeout()\fR returns 1 on success. .PP If any of the function is passed the NULL pointer for the session \fBs\fR, 0 is returned. .SH BUGS .IX Header "BUGS" The data type long is typically 32 bits on many systems, hence the old functions \fBSSL_SESSION_get_time()\fR and \fBSSL_SESSION_set_time()\fR are not always Y2038 safe. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBssl\fR\|(7), \&\fBSSL_CTX_set_timeout\fR\|(3), \&\fBSSL_get_default_timeout\fR\|(3) .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2001\-2024 The OpenSSL Project Authors.
