Convert a time between Nigeria (UTC+1) and your own zone, and find the hours where both working days overlap.
Every time zone is a fixed offset from UTC, so converting is an addition followed by a modulo to wrap past midnight. The overlap figure intersects both locations' 09:00-17:00 windows to show how many hours are genuinely available for a live meeting. Times for Nigeria. Scheduling across zones from memory is how meetings get booked at 03:00; the overlap window is the number that actually matters.
