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.
