Issue with getting closest meeting

Trouble with getting the closest available meeting. The program would only take the **first** meeting of the **day**, not the closest by *time*.

Start by locating the Python code that selects the closest available meeting and reproduce the reported case where only the first meeting of a day is returned. Check the selection logic against meeting times, then verify that the result is the chronologically closest available meeting rather than simply the day's first meeting.
