Tips for US East Coast and Argentina teams
- Argentina doesn't use daylight saving time, so the gap moves by an hour whenever New York 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.
