DESCRIPTION
X509_getm_notBefore() and X509_getm_notAfter() return pointers to the notBefore and notAfter fields of the validity period of the certificate x, respectively. X509_get_notBefore() and X509_get_notAfter() are deprecated aliases implemented as macros.

X509_get0_notBefore() and X509_get0_notAfter() are identical except for the const qualifier on the return type.

X509_CRL_get0_lastUpdate() is misnamed in a confusing way: it returns a pointer to the thisUpdate field of the crl, indicating the time when this crl was issued.

X509_CRL_get0_nextUpdate() returns a pointer to the nextUpdate field of the crl, indicating the time when issuing the subsequent CRL will be due.

X509_CRL_get_lastUpdate() and X509_CRL_get_nextUpdate() are deprecated and identical except for the const qualifier on the argument and on the return type.

X509_set1_notBefore(), X509_set1_notAfter(), X509_CRL_set1_lastUpdate(), and X509_CRL_set1_nextUpdate() set the notBefore, notAfter, thisUpdate (sic!), or nextUpdate field of x or crl, respectively, to a deep copy of tm and free the ASN1_TIME value that they replace.

X509_set_notBefore(), X509_set_notAfter(), X509_CRL_set_lastUpdate(), and X509_CRL_set_nextUpdate() are deprecated aliases.

RETURN VALUES
The get functions return internal pointers which must not be freed by the application, or NULL if the requested field is not available. They may crash with a NULL pointer access if x or crl is NULL.

The set functions return 1 on success or 0 on failure. They fail if x is NULL or does not contain a validity substructure, if crl is NULL, or if ASN1_STRING_dup(3) fails.

Except for some cases of ASN1_STRING_dup(3) failure, these functions do not support determining reasons for failure with ERR_get_error(3).
