.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "X509_CMP_TIME 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
X509_cmp_time, X509_cmp_current_time, X509_time_adj, X509_time_adj_ex \- X509 time functions 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 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.

Header "BUGS" Unlike many standard comparison functions, X509_cmp_time() and \fBX509_cmp_current_time() return 0 on error. 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.
