+ * 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 {
