=head1 NAME
|
|
|
|
X509_cmp_time, X509_cmp_current_time, X509_time_adj, X509_time_adj_ex
|
|
- X509 time functions
|
|
|
|
=head1 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);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_cmp_time() compares the ASN1_TIME in B<asn1_time> with the time
|
|
in <cmp_time>. X509_cmp_current_time() compares the ASN1_TIME in
|
|
B<asn1_time> with the current time, expressed as time_t. B<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 B<asn1_time> to the time
|
|
B<offset_day> and B<offset_sec> after B<in_tm>.
|
|
|
|
X509_time_adj() sets the ASN1_TIME structure B<asn1_time> to the time
|
|
B<offset_sec> after B<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 B<asn1_time> is NULL, a new ASN1_TIME structure
|
|
is allocated and returned.
|
|
|
|
In all methods, if B<in_tm> is NULL, the current time, expressed as
|
|
time_t, is used.
|
|
|
|
=head1 BUGS
|
|
|
|
Unlike many standard comparison functions, X509_cmp_time() and
|
|
X509_cmp_current_time() return 0 on error.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_cmp_time() and X509_cmp_current_time() return -1 if B<asn1_time>
|
|
is earlier than, or equal to, B<cmp_time> (resp. current time), and 1
|
|
otherwise. These methods return 0 on error.
|
|
|
|
X509_time_ad() and X509_time_adj_ex() return a pointer to the updated
|
|
ASN1_TIME structure, and NULL on error.
