Hamburg is 11 hours ahead of Honolulu
There is no standard 8-to-6 overlap. Someone joins early or late.
Honolulu and Hamburg have no natural overlap. The 11-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Honolulu wraps up and leaves notes for Hamburg to pick up as their day begins. The difference isn't constant year-round: Hamburg adjusts for daylight saving while Honolulu holds steady.
