X509_CMP_TIME(3)		    OpenSSL		      X509_CMP_TIME(3)

NAME
       X509_cmp_time, X509_cmp_current_time, X509_time_adj, X509_time_adj_ex -
       X509 time functions

SYNOPSIS
	int X509_cmp_time(const	ASN1_TIME *asn1_time, time_t *in_tm);
	int X509_cmp_current_time(const	ASN1_TIME *asn1_time);
	ASN1_TIME *X509_time_adj(ASN1_TIME *asn1_time, long offset_sec,	time_t *in_tm);
	ASN1_TIME *X509_time_adj_ex(ASN1_TIME *asn1_time, int offset_day, long
				    offset_sec,	time_t *in_tm);

DESCRIPTION
       X509_cmp_time() compares	the ASN1_TIME in asn1_time with	the time in
       <cmp_time>. X509_cmp_current_time() compares the	ASN1_TIME in asn1_time
       with the	current	time, expressed	as time_t. asn1_time must satisfy the
       ASN1_TIME format	mandated by RFC	5280, i.e., its	format must be either
       YYMMDDHHMMSSZ or	YYYYMMDDHHMMSSZ.

       X509_time_adj_ex() sets the ASN1_TIME structure asn1_time to the	time
       offset_day and offset_sec after in_tm.

       X509_time_adj() sets the	ASN1_TIME structure asn1_time to the time
       offset_sec after	in_tm. This method can only handle second offsets up
       to the capacity of long,	so the newer X509_time_adj_ex()	API should be
       preferred.

       In both methods,	if asn1_time is	NULL, a	new ASN1_TIME structure	is
       allocated and returned.

       In all methods, if in_tm	is NULL, the current time, expressed as
       time_t, is used.

BUGS
       Unlike many standard comparison functions, X509_cmp_time() and
       X509_cmp_current_time() return 0	on error.

RETURN VALUES
       X509_cmp_time() and X509_cmp_current_time() return -1 if	asn1_time is
       earlier than, or	equal to, cmp_time (resp. current time), and 1
       otherwise. These	methods	return 0 on error.

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