.Sh DESCRIPTION
.Fn X509_getm_notBefore
and
.Fn X509_getm_notAfter
return pointers to the
.Fa notBefore
and
.Fa notAfter
fields of the validity period of the certificate
.Fa x ,
respectively.
.Pp
.Fn X509_get0_notBefore
and
.Fn X509_get0_notAfter
are identical except for the const qualifier on the return type.
.Pp
.Fn X509_CRL_get0_lastUpdate
and
.Fn X509_CRL_get0_nextUpdate
return pointers to the
.Fa lastUpdate
and
.Fa nextUpdate
fields of
.Fa crl .
.Pp
.Fn X509_set1_notBefore ,
.Fn X509_set1_notAfter ,
.Fn X509_CRL_set1_lastUpdate ,
and
.Fn X509_CRL_set1_nextUpdate
set the
.Fa notBefore ,
.Fa notAfter ,
.Fa lastUpdate ,
or
.Fa nextUpdate
field of
.Fa x
or
.Fa crl ,
respectively, to a deep copy of
.Fa tm
and free the
.Vt ASN1_TIME
value that they replace.
.Sh RETURN VALUES
.Fn X509_get0_notBefore ,
.Fn X509_get0_notAfter ,
.Fn X509_getm_notBefore ,
.Fn X509_getm_notAfter ,
.Fn X509_CRL_get0_lastUpdate ,
