Three time zone hubs for global accessibility: Asia Pacific; Africa, Europe, and Middle East; and the Americas. The coloured bars represent the schedule range of each hub in 6 representative time zones. For each time zone, a blue box indicates the timing corresponding to the recommended hub. For example, researchers based in New Zealand (NZST) can attend hub 1 during 14:00–18:00 (local time). They will be joined in this hub by researchers from Bangladesh (BST) for whom the content will happen 8:00–12:00 (local time). The green dashed rectangles cover typical working hours, which often fall within the 8:00–18:00 range. The 3 time zone hubs make it possible to schedule 4 hours of content each day while remaining within typical working hours for nearly all time zones. NZST: New Zealand Standard Time (UTC+12); BST: Bangladesh Standard Time (UTC+6); PST: Pakistan Standard Time (UTC+5); GMT: Greenwich Mean Time (UTC+0); BRT: Brasília Time (UTC−3); AKDT: Alaska Daylight Time (UTC−8).
