I'd like to add to the Slack message that notifies that a Github workflow run has finished, the total duration it took to run.

Does anyone know how can it be achieved? I couldn't find "total duration" in any of the contexts...

I don't think it's available from a context, but you could do it with two separate run steps:

  1. Store the current time as a timestamp (first step in workflow):

    - name: Set start timestamp
  id: start
  run: |
    printf 'timestamp=%(%s)T\n' >> "$GITHUB_OUTPUT"

  2. Calculate difference (at end of workflow):

    - name: Calculate duration
  run: |
    printf -v now '%(%s)T'
    duration=$((now - ${{ steps.start.outputs.timestamp }}))
    # Do something with duration, set as output to then use in Slack message
    # or similar

This puts the duration in seconds into the duration variable.
