Clock time and solar time in Vietnam
A country's clocks are a political choice, not an astronomical one, so they rarely line up with its own sun. Measured against local solar time, the clock in Hanoi runs 3 minutes behind the sun.
Solar noon there falls 3 minutes before 12:00 on the clock.
How much daylight changes through the year
Daylight is governed by latitude, not by the clock. Hanoi, at 21.0° north, gets 13 hours 25 minutes of daylight on the longest day of the year and 10 hours 51 minutes on the shortest.
Ho Chi Minh City, at 10.8° north, gets 12 hours 45 minutes of daylight on the longest day of the year and 11 hours 29 minutes on the shortest. So the annual swing between longest and shortest day is 2 hours 34 minutes in Hanoi against 1 hour 16 minutes in Ho Chi Minh City, within the same country.
