[tz] EST/EDT vs AEST/AEDT in AQ

[John Hawkinson]

Hang on here.
Choosing to not use 'D' to mean something different from everything else
is not "overloading" the field. 

If I understand correctly, the region in question, Lord Howe, has three
seasonal variations.

If there is a Standard and a Daylight and a Half, I think it makes
sense for them to use different abbreviations. As we noted earlier,
one of the frequent use cases of the abbrevs is for a user to type
'date' and use the abbrev output to determine which seasonal variation
we are in (in my case, whether I am in US/Eastern's Eastern Daylight
Time or Eastern Standard Time).

On the other hand, I don't think LHDT/LHST/LHHDT is a good choice,
because like it or not, some people get confused by the 'D'. Be liberal
in what you accept, but rigorous in what you send.

I think LHDT/LHST/LHHT was originaly proposed? To me that would be better.
What is the downside to it?

Maybe that's what we're discussing? I can't tell, the discussion has
gotten so abstract without concrete examples and looking back at the
last 50 or so tz messages that mention Lord Howe is not supre-clear.
