Portland is 9 hours behind Lagos
Best overlap: 5:00 PM to 6:00 PM in Lagos is 8:00 AM to 9:00 AM in Portland.
Both teams are at their desks between 5:00 PM to 6:00 PM in Lagos and 8:00 AM to 9:00 AM in Portland. Portland is 9 hours behind Lagos, which leaves a narrow 1-hour window. Treat 5:00 PM in Lagos (8:00 AM in Portland) as the time and build around it. One seasonal catch: Portland springs forward and falls back, but Lagos doesn't, so the gap changes by an hour for several months of the year.
