+=head1 NAME
+
+X509_cmp_time - X509 time functions
+
+=head1 SYNOPSIS
+
+ X509_cmp_time(const ASN1_TIME *asn1_time, time_t *cmp_time);
+
+=head1 DESCRIPTION
+
+X509_cmp_time() compares the ASN1_TIME in B<asn1_time> with the time in
+<cmp_time>.
+
+B<asn1_time> must satisfy the ASN1_TIME format mandated by RFC 5280, i.e.,
+its format must be either YYMMDDHHMMSSZ or YYYYMMDDHHMMSSZ.
+
+If B<cmp_time> is NULL the current time is used.
+
+=head1 BUGS
+
+Unlike many standard comparison functions, X509_cmp_time returns 0 on error.
+
+=head1 RETURN VALUES
+
+X509_cmp_time() returns -1 if B<asn1_time> is earlier than, or equal to,
+B<cmp_time>, and 1 otherwise. It returns 0 on error.
