Beijing is 7 hours ahead of Geneva
Best overlap: 8:00 AM to 11:00 AM in Geneva is 3:00 PM to 6:00 PM in Beijing.
Both teams are at their desks between 8:00 AM to 11:00 AM in Geneva and 3:00 PM to 6:00 PM in Beijing. Roughly 3 hours of shared hours means scheduling takes a little care — 8:00 AM in Geneva / 3:00 PM in Beijing is a safe default. A quick caveat — Geneva's clocks move for daylight saving and Beijing's don't, so the times here are right for only part of the year.
