San Diego is 12.5 hours behind Colombo

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

Colombo and San Diego are too far apart in time (12.5 hours) for their workdays to line up during regular hours. For anything urgent, agree on an early-morning or late-night bridge hour in advance so nobody's caught off guard. 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.
