Give it a search window, a meeting length, and for each participant a list of busy blocks — start and end, nothing else — and it returns the windows in which the meeting fits. Each participant carries their own IANA timezone and working hours, so nine-to-five means nine-to-five where they are, across daylight saving changes, and a meeting is only offered when it lies entirely inside one working-hours block for everyone counted as present.
