Unless you can show that Ha Noi and Ho Chi Minh City have not used the same local time for some period (a few minutes would be enough) since 1970 an additional zone won't be created for it either. (Differences before 1970 could just possibly be used, sometime in the future, so research into actyal time usage back into history is always useful - if backed by good references.)
The Wikipedia page, <https://en.wikipedia.org/wiki/Time_in_Vietnam>, says that they were different. For example, from 1968 to 1975, North Vietnam (Hanoi) was on UTC+07:00, and from 1960 to 1975, South Vietnam (Saigon, or Ho Chi Minh City) was on UTC+08:00. --apb (Alan Barrett)
