    sys/netgraph         ng_source.c ng_source.h 
  Log:
  Add "settimestamp" and "gettimestamp" messages, providing the the ability
  to embed a timestamp (struct timeval) in outgoing packets.  The message
  specifies the offset at which the timestamp should be inserted.
  
  NG_SOURCE(4) gives an example usage that queues an ICMP packet.  Using that
  example, the following command will insert a timestamp in the ICMP's data
  payload:
  
    ngctl msg src0: settimestamp '{ offset=0x2a flags=1 }'
