Enriched Operating Guide
Ho Chi Minh City and Phnom Penh share the same clock, giving your teams a full 09:00–17:00 live overlap on both sides. No offset means neither city carries a time-of-day burden — the compromise window is balanced. Live coordination scores 8/10 with low async risk, so same-day decisions and recurring slots are realistic. Local lunch norms in both cities compress the productive band, making the nominal overlap more fragile than the zero-offset headline suggests. Keep local calendars visible to avoid mistaking the full window for the usable one.
Overlap And Burden
Your teams share a 09:00–17:00 overlap window with zero time difference to manage. Neither city bears an off-peak burden — the live band falls inside standard hours on both sides. The real constraint is lunch: the overlap is fully balanced in clock terms but more fragile in practice, since each city's midday pause splits the window into separate morning and afternoon blocks.
Meeting Recommendation
Best window: 09:30–11:30 and 13:30–16:00 in both cities, avoiding the shared lunch corridor. For relationship-building calls with Phnom Penh counterparts, favor the morning block when formal context carries more weight. A fixed recurring slot is sustainable inside either half of the split window, giving your teams a predictable daily decision band.
