• Included the relevant configuration snippet

This is my process-compose.yaml:

version: "0.5"

processes:
  time:
    working_dir: .
    command: "while :; do sleep 1; date; done"

• Included the relevant process-compose log (log location: process-compose info)

The process-compose log is basically empty:
