Look at apps/x509.c. Specifically how "openssl x509 -dates" is implemented.
else if (startdate == i)
{
BIO_puts(STDout,"notBefore=");
ASN1_TIME_print(STDout,X509_get_notBefore(x));
BIO_puts(STDout,"\n");
}
else if (enddate == i)
{
BIO_puts(STDout,"notAfter=");
ASN1_TIME_print(STDout,X509_get_notAfter(x));
BIO_puts(STDout,"\n");
}
