This class provides the timestamp token info resulting from a successful timestamp request, as defined in RFC 3161. The timestampTokenInfo ASN.1 type has the following definition:

    TSTInfo ::= SEQUENCE {
        version                INTEGER  { v1(1) },
        policy                 TSAPolicyId,
        messageImprint         MessageImprint,
          -- MUST have the same value as the similar field in
          -- TimeStampReq
        serialNumber           INTEGER,
         -- Time-Stamping users MUST be ready to accommodate integers
         -- up to 160 bits.
        genTime                GeneralizedTime,
        accuracy               Accuracy                 OPTIONAL,
        ordering               BOOLEAN             DEFAULT FALSE,
        nonce                  INTEGER                  OPTIONAL,
          -- MUST be present if the similar field was present
          -- in TimeStampReq.  In that case it MUST have the same value.
        tsa                    [0] GeneralName          OPTIONAL,
        extensions             [1] IMPLICIT Extensions  OPTIONAL }

    Accuracy ::= SEQUENCE {
        seconds        INTEGER           OPTIONAL,
        millis     [0] INTEGER  (1..999) OPTIONAL,
        micros     [1] INTEGER  (1..999) OPTIONAL  }
