```
byte[] timeStamp(SignatureInfo signatureInfo,
                 byte[] data,
                 RevocationData revocationData)
          throws Exception
```
    Gives back the encoded time-stamp token for the given array of data bytes. We assume that the time-stamp token itself contains its full certificate chain required for proper validation.
    
    Parameters:
    
    data - the data to be time-stamped.
    
    revocationData - the optional container that needs to be filled up with the revocation data used to validate the TSA certificate chain.
    
    Returns:
    
    the DER encoded time-stamp token.
    
    Throws:
    
    Exception - in case something went wrong.
