San Diego is 11 hours behind Dubai

There is no standard 8-to-6 overlap. Someone joins early or late.

Given San Diego is 11 hours behind Dubai, the realistic answer is that there's no convenient shared slot during normal business hours. Catch the edges of the day: the last hour for Dubai or the first hour for San Diego is usually the least painful option. Because only San Diego changes its clocks, the overlap above isn't fixed; expect a one-hour shift when San Diego enters or leaves daylight saving.
