NAME

     X509_cmp_time - X509 time functions

SYNOPSIS

      X509_cmp_time(const ASN1_TIME *asn1_time, time_t *cmp_time);

DESCRIPTION

     X509_cmp_time() compares the ASN1_TIME in asn1_time with the
     time in <cmp_time>.

     asn1_time must satisfy the ASN1_TIME format mandated by RFC
     5280, i.e., its format must be either YYMMDDHHMMSSZ or
     YYYYMMDDHHMMSSZ.

     If cmp_time is NULL the current time is used.

BUGS

     Unlike many standard comparison functions, X509_cmp_time
     returns 0 on error.

RETURN VALUES

     X509_cmp_time() returns -1 if asn1_time is earlier than, or
     equal to, cmp_time, and 1 otherwise. It returns 0 on error.
