Tips for India and US West Coast teams
- India doesn't use daylight saving time, so the gap moves by an hour whenever San Francisco changes its clocks. Recurring meetings set in one place's time will shift for the other.
- With no shared standard hours, agree which side stretches its day, and rotate the inconvenient slot so it doesn't always fall on the same people.
- Keep live meetings for decisions that need discussion; use written handoffs at the end of each day for everything else.
