NAME

6       X509_cmp_time, X509_cmp_current_time, X509_time_adj, X509_time_adj_ex -
7       X509 time functions

SYNOPSIS

10        int X509_cmp_time(const ASN1_TIME *asn1_time, time_t *in_tm);
11        int X509_cmp_current_time(const ASN1_TIME *asn1_time);
12        ASN1_TIME *X509_time_adj(ASN1_TIME *asn1_time, long offset_sec, time_t *in_tm);
13        ASN1_TIME *X509_time_adj_ex(ASN1_TIME *asn1_time, int offset_day, long
14                                    offset_sec, time_t *in_tm);

DESCRIPTION

17       X509_cmp_time() compares the ASN1_TIME in asn1_time with the time in
18       <cmp_time>. X509_cmp_current_time() compares the ASN1_TIME in asn1_time
19       with the current time, expressed as time_t. asn1_time must satisfy the
20       ASN1_TIME format mandated by RFC 5280, i.e., its format must be either
21       YYMMDDHHMMSSZ or YYYYMMDDHHMMSSZ.
22
23       X509_time_adj_ex() sets the ASN1_TIME structure asn1_time to the time
24       offset_day and offset_sec after in_tm.
25
26       X509_time_adj() sets the ASN1_TIME structure asn1_time to the time
27       offset_sec after in_tm. This method can only handle second offsets up
28       to the capacity of long, so the newer X509_time_adj_ex() API should be
29       preferred.
30
31       In both methods, if asn1_time is NULL, a new ASN1_TIME structure is
32       allocated and returned.
33
34       In all methods, if in_tm is NULL, the current time, expressed as
35       time_t, is used.
36

BUGS

38       Unlike many standard comparison functions, X509_cmp_time() and
39       X509_cmp_current_time() return 0 on error.
40

RETURN VALUES

42       X509_cmp_time() and X509_cmp_current_time() return -1 if asn1_time is
43       earlier than, or equal to, cmp_time (resp. current time), and 1
44       otherwise. These methods return 0 on error.
45
46       X509_time_adj() and X509_time_adj_ex() return a pointer to the updated
47       ASN1_TIME structure, and NULL on error.
