      # systemctl stop systemd-timesyncd

      Use the dispatch router as the other peer.

      $ router/qdrouterd

      Get cli-proton-python and start it. https://github.com/rh-messaging/cli-proton-python

      $ python3 -m venv py3venv
      $ source py3venv/bin/activate
      $ pip install cli-proton-python
      $ PN_TRACE_FRM=1 cli-proton-python-sender --conn-heartbeat=5
      

      Wait a moment, then change time going forward and connection then fails. If you move it backward instead, heartbeats stop flowing.

      # date --set='+30 minutes'

      Observe the following connection failure
