The hours that work for both Lisbon and Ho Chi Minh City are 8:00 AM to 12:00 PM (Lisbon) and 2:00 PM to 6:00 PM (Ho Chi Minh City). Roughly 4 hours of shared hours means scheduling takes a little care — 8:00 AM in Lisbon / 2:00 PM in Ho Chi Minh City is a safe default. A quick caveat — Lisbon's clocks move for daylight saving and Ho Chi Minh City's don't, so the times here are right for only part of the year.
