 public final class Timestamp extends Object implements Serializable 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.- Since:

Constructor Detail- 
Timestamppublic Timestamp(Date timestamp, CertPath signerCertPath) Constructs a Timestamp.- Parameters:
- timestamp- is the timestamp's date and time. It must not be null.
- signerCertPath- is the TSA's certificate path. It must not be null.
- Throws:
- NullPointerException- if timestamp or signerCertPath is null.

Method Detail- 
getTimestamppublic Date getTimestamp() Returns the date and time when the timestamp was generated.- Returns:
- The timestamp's date and time.
 
 - 
getSignerCertPathpublic CertPath getSignerCertPath() Returns the certificate path for the Timestamping Authority.- Returns:
- The TSA's certificate path.
 
 - 
hashCodepublic 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.- Overrides:
- hashCodein class- Object
- Returns:
- a hash code value for this timestamp.

- Object.equals(java.lang.Object),- System.identityHashCode(java.lang.Object)
 
 - 
equalspublic 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.- Overrides:
- equalsin class- Object
- Parameters:
- obj- the object to test for equality with this timestamp.
- Returns:
- true if the timestamp are considered equal, false otherwise.
