Based on the below I suggest to add EDT and CDT. It is the minimal change, if counted in quantity of changed letters during DST, to achieve what the thread opener wanted: Acronyms that allow to differentiate between zones that in winter are one and in summer are two. 1) (A)EST and (A)EDT 2) (A)CST and (A)CDT On Tue, Apr 2, 2013 at 12:56 AM, Tobias Conradi <tobias.conradi@gmail.com> wrote:

So the issues here is 'common usage' vs Federal government usage vs State government usage.
Maybe not even that. It is about choosing any set of acronyms that differentiates between different offsets.
Common usage, Paul's survey: http://mm.icann.org/pipermail/tz/2012-October/018364.html AEST AEDT CST CDT WST WDT
Federal govt http://australia.gov.au/about-australia/our-country/time#daylightsaving AEST AEDT ACST ACDT AWST
IANA timezone database ftp://ftp.iana.org/tz/data/australasia EST CST WST
No markers for DST at all.
