Tips for India and UK teams
- India doesn't use daylight saving time, so the gap moves by an hour whenever London changes its clocks. Recurring meetings set in one place's time will shift for the other.
- There's enough shared time for a daily meeting. Booking it in the middle of the window leaves room for follow-ups on both sides.
