"NAME"
X509_cmp_time, X509_cmp_current_time, X509_time_adj, X509_time_adj_ex \- X509 time functions
"SYNOPSIS"
Header "SYNOPSIS" .Vb 5
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);
.Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBX509_cmp_time() compares the \s-1ASN1_TIME\s0 in asn1_time with the time
in <cmp_time>. X509_cmp_current_time() compares the \s-1ASN1_TIME\s0 in
\fBasn1_time with the current time, expressed as time_t. asn1_time
must satisfy the \s-1ASN1_TIME\s0 format mandated by \s-1RFC 5280,\s0 i.e., its
format must be either \s-1YYMMDDHHMMSSZ\s0 or \s-1YYYYMMDDHHMMSSZ.\s0
\fBX509_time_adj_ex() sets the \s-1ASN1_TIME\s0 structure asn1_time to the time \fBoffset_day and offset_sec after in_tm.
\fBX509_time_adj() sets the \s-1ASN1_TIME\s0 structure asn1_time to the time \fBoffset_sec after in_tm. This method can only handle second offsets up to the capacity of long, so the newer X509_time_adj_ex() \s-1API\s0 should be preferred.
In both methods, if asn1_time is \s-1NULL,\s0 a new \s-1ASN1_TIME\s0 structure is allocated and returned.
In all methods, if in_tm is \s-1NULL,\s0 the current time, expressed as time_t, is used.
"BUGS"
Header "BUGS" Unlike many standard comparison functions, X509_cmp_time() and
\fBX509_cmp_current_time() return 0 on error.
"RETURN VALUES"
Header "RETURN VALUES" \fBX509_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.
\fBX509_time_adj() and X509_time_adj_ex() return a pointer to the updated \s-1ASN1_TIME\s0 structure, and \s-1NULL\s0 on error.
