Hyderabad is 12.5 hours ahead of San Diego

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

San Diego and Hyderabad are 12.5 hours apart, and that gap is wide enough that their normal 9-to-5 workdays never quite touch. If you meet regularly, fix one off-hours slot and rotate it between San Diego and Hyderabad so the burden doesn't fall on one team. These times hold for most of the year, but San Diego's daylight saving (which Hyderabad doesn't use) shifts them by an hour twice annually.
