Tips for UK and Singapore teams
- Singapore 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.
- The shared window is only 1h. Protect it for conversations that need everyone live, and move status updates to writing.
