Tips for US West Coast and Mexico teams
- Mexico 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.
- 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.
