Adelaide is 14.5 hours ahead of Lima
There is no standard 8-to-6 overlap. Someone joins early or late.
Lima and Adelaide have no natural overlap. The 14.5-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Lima wraps up and leaves notes for Adelaide to pick up as their day begins. A quick caveat — Adelaide's clocks move for daylight saving and Lima's don't, so the times here are right for only part of the year.
