San Diego is 10 hours behind Riyadh

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

Coordinating Riyadh and San Diego is tricky: 10 hours of separation means their standard hours don't intersect. Async-first is your friend here. Reserve real-time meetings for the rare occasions someone can log on before or after hours. Heads up: because San Diego changes its clocks and Riyadh doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
