there is no document saying that North Vietnam accepted Asia/Bangkok as a representative time zone

There does not need to be such a document, as we're not aiming to reflect "acceptance" of anything. All our data would assert is that Hanoi's clocks have matched Bangkok's since 1970. It could just as easily be said that Bangkok's clocks have matched Hanoi's for the same period; the two statements are equivalent. It doesn't matter to us whether this is due to cooperation, coercion, or coincidence. The direction of the link in our data would simply be based on the relative populations, and Bangkok is the larger city. -- Tim Parenti
