VNG broadcasted time in binary coded decimal, during seconds 21-58. It also broadcasts DUT-1 information during seconds 1-16. Tones are usually of 1 kHz. VNG also broadcasted speaking time broadcasts as well.
It was shut down December 31, 2002, due to funding insufficiencies. Many scientific and astronomic users of the service were somewhat inconvenienced at the shutdown, and daytime reception of time signal services is generally thought of as rather poor, as the nearest time signal services are BPM in China and WWVH (or WWV) from Australia.
