Doha is 10 hours ahead of San Diego

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

Doha is 10 hours ahead of San Diego, which is far enough that a normal 9-to-5 in one city never reaches the other's working hours. One practical option: San Diego dials in early while it's still late afternoon or evening in Doha. Keep an eye on the calendar — San Diego observes daylight saving and Doha doesn't, which nudges this window by an hour twice a year.
