Casablanca is 11 hours behind Wellington
There is no standard 8-to-6 overlap. Someone joins early or late.
Practically speaking, Wellington and Casablanca never share office hours; 11 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Casablanca can catch the tail end of the day in Wellington, or the other way round. Bear in mind Wellington shifts for daylight saving while Casablanca stays fixed — recheck these hours after each clock change.
