I've never heard of EDST. Their are four zones in the 48 contiguous
states: EST (Eastern Standard Time), CST (Central Standard Time),
MST (Mountain Standard Time) and PST (Pacific Standard Time).
During half the year, the S (Standard) becomes D (Daylight). I
think EDST was just an attempt to combine the D/S into a collective
form.
One thing I though was screwy about Oz time was Western Australia
being off-alignment from other zones by 30 minutes. The same thing
happens in India. I'm not quite sure what logic is involved there.
