      org.bouncycastle.asn1.cms.BinaryTime

All Implemented Interfaces:

ASN1Encodable, Encodable

public class BinaryTime

extends ASN1Object

RFC 6019 type — the unsigned integer count of seconds since 1970-01-01T00:00:00Z (UTC). BinaryTime ::= INTEGER (0..MAX) Used by other LAMPS specifications that need a compact, monotonically increasing time value as part of an ASN.1 structure (e.g. RFC 9763 RequesterCertificate.requestTime). The companion CMS signed attribute OID is available as PKCSObjectIdentifiers.pkcs_9_at_binarySigningTime.

Constructor Summary

BinaryTime(ASN1Integer time)

BinaryTime(java.util.Date date)
Construct a BinaryTime carrying the seconds-since-epoch of the supplied Date.

BinaryTime(long seconds)
Construct a BinaryTime carrying the supplied count of seconds since 1970-01-01T00:00:00Z (UTC).

Method Summary

static BinaryTime	getInstance(java.lang.Object obj)
ASN1Integer	getTime()
ASN1Primitive	toASN1Primitive() Method providing a primitive representation of this object suitable for encoding.
java.util.Date	toDate() Convert the encoded value to a Date.

Constructor Detail

BinaryTime

public BinaryTime(java.util.Date date)

Construct a BinaryTime carrying the seconds-since-epoch of the supplied Date. Sub-second components are discarded by truncation toward negative infinity (consistent with Date.getTime() / 1000).

Throws:

java.lang.IllegalArgumentException - if is before the epoch (RFC 6019 prohibits negative values).

BinaryTime

public BinaryTime(long seconds)

Construct a BinaryTime carrying the supplied count of seconds since 1970-01-01T00:00:00Z (UTC).

Throws:

java.lang.IllegalArgumentException - if is negative.

BinaryTime

public BinaryTime(ASN1Integer time)

Method Detail

getInstance

public static BinaryTime getInstance(java.lang.Object obj)

getTime

public ASN1Integer getTime()

Returns:

the encoded value as a count of seconds since the Unix epoch. May exceed on a wildly out-of-range encoding; callers that only need a Date may prefer toDate() which rejects unrepresentable values.

toDate

public java.util.Date toDate()

Convert the encoded value to a Date.

Throws:

java.lang.ArithmeticException - if the seconds value does not fit in a after multiplication by 1000.

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Description copied from class: ASN1Object

Method providing a primitive representation of this object suitable for encoding.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
