X509_CMP_TIME(3)      DragonFly Library Functions Manual      X509_CMP_TIME(3)

NAME
     X509_cmp_time, X509_cmp_current_time, X509_time_adj_ex, X509_time_adj --
     ASN.1 Time utilities

SYNOPSIS
     #include <openssl/x509.h>

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

     int
     X509_cmp_current_time(const ASN1_TIME *asn1_time);

     ASN1_TIME *
     X509_time_adj_ex(ASN1_TIME *asn1_time, int offset_day, long offset_sec,
	 time_t *in_tm);

     ASN1_TIME *
     X509_time_adj(ASN1_TIME *asn1_time, long offset_sec, time_t *in_tm);

DESCRIPTION
     X509_cmp_time() parses asn1_time with ASN1_time_parse(3) and compares it
     to cmp_time.  X509_cmp_current_time() compares it to the current time.

     X509_time_adj_ex() sets asn1_time to a time offset_day and offset_sec
     later than in_tm.	X509_time_adj() does the same with a 0 day offset.  If
     asn1_time is NULL, a new ASN1_TIME structure is allocated and returned.

     In all functions, if in_tm is NULL, the current time is used.

RETURN VALUES
     X509_cmp_time() and X509_cmp_current_time() return -1 if asn1_time is
     earlier than or equal to cmp_time, 1 if it is later, or 0 on error.

     X509_time_adj_ex() and X509_time_adj() return a pointer to the updated
     ASN1_TIME structure or NULL on error.
