Class BinaryTime

java.lang.Object

org.bouncycastle.asn1.ASN1Object

org.bouncycastle.asn1.cms.BinaryTime

All Implemented Interfaces:

org.bouncycastle.asn1.ASN1Encodable, org.bouncycastle.util.Encodable

public class BinaryTime
extends org.bouncycastle.asn1.ASN1Object

RFC 6019 BinaryTime 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 id-aa-binarySigningTime CMS signed attribute OID is available as PKCSObjectIdentifiers.pkcs_9_at_binarySigningTime.

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 date 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 seconds is negative.

BinaryTime

public BinaryTime(org.bouncycastle.asn1.ASN1Integer time)

Method Detail

getInstance

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

getTime

public org.bouncycastle.asn1.ASN1Integer getTime()

Returns:

the encoded value as a count of seconds since the Unix epoch. May exceed Long.MAX_VALUE 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 long after multiplication by 1000.
