Problem with WifiESP WidiUdpNtp example

I have not altered the code but I am getting 0 seconds since 1900.

That suggests that the format of these NTP packets have changed since this sketch was written.

packet received Seconds since Jan 1 1900 = 0 Unix time = 2085978496 The UTC time is 6:28:16 15

      // The timestamp starts at byte 40 of the received packet and is four bytes, or two words, long. 
      // First, esxtract the two words:
      uint16_t nHighWord = word(arrayBuffer[40], arrayBuffer[41]),
                nLowWord = word(arrayBuffer[42], arrayBuffer[43]);

Can anyone tell me what this code should be changed to

Is this page accurate for NTP packets?

It appears to me that the time stamp should start at byte 32 not byte 40?

I altered this example sketch to dump the contents of the buffer and this is what I am getting in serial monitor:

I don't understand what I am getting from the NTP server.

Either way this example sketch is reading the empty part of the buffer to get the seconds since 1900!
