13X509_cmp_time() compares the ASN1_TIME in B<asn1_time> with the time in
14<cmp_time>.
15
16B<asn1_time> must satisfy the ASN1_TIME format mandated by RFC 5280, i.e.,
17its format must be either YYMMDDHHMMSSZ or YYYYMMDDHHMMSSZ.
18
19If B<cmp_time> is NULL the current time is used.

24
25=head1 RETURN VALUES
26
27X509_cmp_time() returns -1 if B<asn1_time> is earlier than, or equal to,
28B<cmp_time>, and 1 otherwise. It returns 0 on error.
