Timestamp

public final class Timestamp
extends Object implements Serializable

java.lang.Object
↳	java.security.Timestamp

This class encapsulates information about a signed timestamp. It is immutable. It includes the timestamp's date and time as well as information about the Timestamping Authority (TSA) which generated and signed the timestamp.

Summary

Public constructors
`Timestamp(Date timestamp, CertPath signerCertPath)` Constructs a Timestamp.

Public methods
`boolean`	`equals(Object obj)` Tests for equality between the specified object and this timestamp.
`CertPath`	`getSignerCertPath()` Returns the certificate path for the Timestamping Authority.
`Date`	`getTimestamp()` Returns the date and time when the timestamp was generated.
`int`	`hashCode()` Returns the hash code value for this timestamp.
`String`	`toString()` Returns a string describing this timestamp.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public constructors

Timestamp

Added in API level 1

public Timestamp (Date timestamp, 
                CertPath signerCertPath)

Constructs a Timestamp.

Parameters
`timestamp`	`Date`: is the timestamp's date and time. It must not be null.
`signerCertPath`	`CertPath`: is the TSA's certificate path. It must not be null.

Throws
`NullPointerException`	if timestamp or signerCertPath is null.

Public methods

equals

Added in API level 1

public boolean equals (Object obj)

Tests for equality between the specified object and this timestamp. Two timestamps are considered equal if the date and time of their timestamp's and their signer's certificate paths are equal.

Parameters
`obj`	`Object`: the object to test for equality with this timestamp.

Returns
`boolean`	true if the timestamp are considered equal, false otherwise.

getSignerCertPath

Added in API level 1

public CertPath getSignerCertPath ()

Returns the certificate path for the Timestamping Authority.

Returns
`CertPath`	The TSA's certificate path.

getTimestamp

Added in API level 1

public Date getTimestamp ()

Returns the date and time when the timestamp was generated.

Returns
`Date`	The timestamp's date and time.

hashCode

Added in API level 1

public int hashCode ()

Returns the hash code value for this timestamp. The hash code is generated using the date and time of the timestamp and the TSA's certificate path.

Returns
`int`	a hash code value for this timestamp.

toString

Added in API level 1

public String toString ()

Returns a string describing this timestamp.

Returns
`String`	A string comprising the date and time of the timestamp and its signer's certificate.
