I expect CLDR got those abbreviations from us, so they're not really an 
independent source.

It seemed to me that independent sources seem to prefer HST/HDT whereas 
sources derived from the tz database of course prefer HAST/HADT as that 
is what we are using.  This isn't a good situation: the tz database 
should reflect common usage, not set it.

Although the GPO style manual was the tipping point for me, plenty of 
other sources outside tz's orbit use HST/HDT, or call it "Hawaii time" 
even though it's in the Aleutians.  It's not just the Wikipedia page for 
Adak.  See, for example:
