Ottawa is 12 hours behind Jakarta
There is no standard 8-to-6 overlap. Someone joins early or late.
For Jakarta and Ottawa, the standard workday in one city falls outside office hours in the other — that's what 12 hours of distance does. Keep live syncs short and infrequent, and let written updates carry the day-to-day between Jakarta and Ottawa. Because only Ottawa changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Ottawa enters or leaves daylight saving.
