What time would dusk be in Hong Kong

I'm looking for the time of dusk in Hong Kong during March. Please help! (:

The time of dusk for everywhere in the world on the equinox (typically March 21st) is 6:00 pm on a (non-daylight savings) standard time basis.


Note: because the time zones are discrete to the hour (instead of continuous)...the time can vary by about + or - 30 minutes from the theoretical 6:00 pm.
