Anchorage is 10 hours behind Casablanca
There is no standard 8-to-6 overlap. Someone joins early or late.
A 10-hour difference puts Casablanca and Anchorage out of sync — when one team is mid-morning, the other is fast asleep. Consider rotating the inconvenience: one week Casablanca takes the early call, the next week Anchorage does. Remember that Anchorage shifts for daylight saving and Casablanca doesn't, so recalculate the overlap after each clock change.
