Play Montage and "Starting Position"

The “Play Montage” node has a “Starting Position” parameter which does not seem to do anything. I have seen it described as time in seconds and sometimes as a portion of the animation. However, regardless of the value the result looks the same. Can anyone clarify if this parameter works, and if so, what is its unit of measurement and how is it used? Does it get ignored in some cases?

To answer my own question: it seems to be overridden by the “Starting Section” parameter.
