I may need a cafeine break, but I was thinking that I was applying the
calendar and time scales for duration in a consistent way. You add the
scalar of the duration to the start.
The issue was that some folks were converting the calendar scale into a time
scale. In such mixed scale cases (i.e., DTSTART in date-time...effectively a
time scale and the end/DURATION in calendar scale), I would have used the
date-time to determine the calendar scale and then apply the duration to
