NAME

SYNOPSIS

int
ASN1_time_parse(const char *bytes, size_t len, struct tm *tm, int mode);

int
ASN1_time_tm_cmp(struct tm *tm1, struct tm *tm2);

ASN1_TIME *
ASN1_TIME_set_tm(ASN1_TIME *s, struct tm *tm);

DESCRIPTION

The mode parameter must be one of

• 0 to parse a time as specified in RFC 5280 for an X509 object, which may be either a UTC time or a Generalized time.
• V_ASN1_UTCTIME to parse an RFC 5280 format UTC time.
• V_ASN1_GENERALIZEDTIME to parse an RFC 5280 format Generalized time.

The ASN1_time_tm_cmp() function compares two times in tm1 and tm2.

The function ASN1_TIME_set_tm() sets the ASN1_TIME structure s to the time represented by the struct tm value pointed to by tm. If s is NULL, a new ASN1_TIME structure is allocated and returned.

RETURN VALUES

• -1 if the string was invalid for the mode specified.
• V_ASN1_UTCTIME if the string parsed as a valid UTC time.
• V_ASN1_GENERALIZEDTIME if the string parsed as a valid Generalized time.

ASN1_time_tm_cmp() returns

• -1 if tm1 is less than tm2.
• 1 if tm1 is greater than tm2.
• 0 if tm1 is the same as tm2.

ASN1_TIME_set_tm() returns a pointer to an ASN1_TIME structure or NULL if an error occurred.
