       Methodsdefinedhere:
       ---------------------

       __init__(self,pktt)
       Constructor

       Initialize object's private data.

              pktt:  Packet trace object (packet.pktt.Pktt) so this layer has
                     access to the parent layers.

   classNTPExtField(baseobj.BaseObj)
       NTP extension field

       Methodsdefinedhere:
       ---------------------

       __init__(self,unpack)
       Constructor which takes the Unpack object as input

   classNTP_TimeStamp(packet.utils.DateStr)
       NTP timestamp

   classntp4_mode(packet.utils.Enum)
       enum ntp4_mode

       Decode NTP layer.

NTP(pktt)
       Wrapper function to select correct NTP object
