Best overlap: 1:00 PM to 6:00 PM in Auckland is 8:00 AM to 1:00 PM in Ho Chi Minh City.
The overlap falls at 1:00 PM to 6:00 PM in Auckland, or 8:00 AM to 1:00 PM if you're in Ho Chi Minh City.

Because only Auckland changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Auckland enters or leaves daylight saving.
