$ sudo pip install pdml2flow-frame-inter-arrival-time

usage: Calculate inter arrival times of frames in a flow or on an interface
       [-h] [--no_flow] [--frames]

optional arguments:
  -h, --help  show this help message and exit
  --no_flow   Calculate inter arrival time to the previous frame on the
              interface, not in the flow [default: False]
  --frames    Print the frames alongside the inter arrival time [default:
              False]
