Why the time difference exists
The clock in San Francisco is anchored to UTC-8 standard time; Bengaluru works from UTC+5:30 standard time. San Francisco moves its clocks for daylight saving time while Bengaluru keeps the same time all year, so the gap widens and narrows by an hour with the seasons. Geographically the two lie about 14,000 km apart, with Bengaluru to the northwest of San Francisco.
Flying from San Francisco to Bengaluru, your body clock shifts about 11 hours back. In flying terms that's roughly 17 hours in the air, give or take. A quick look at each side's working hours keeps meetings out of the middle of the night.
