=pod =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 with the time in . X509_cmp_current_time() compares the ASN1_TIME in B with the current time, expressed as time_t. B 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 to the time B and B after B. X509_time_adj() sets the ASN1_TIME structure B to the time B after B. 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 is NULL, a new ASN1_TIME structure is allocated and returned. In all methods, if B 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 is earlier than, or equal to, B (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. =head1 COPYRIGHT Copyright 2017 The OpenSSL Project Authors. All Rights Reserved.
