"date -d" parses the timezone itself without the help of tzdata, and it
indeed doesn't know about the AEST timezone. I am therefore reassigning
the bug to coreutils.

Bug#832550: tzdata: Certain zone abbreviations do not support round-trip conversion

[Mark Stafford]

Package: tzdata
Version: 2016f-0+deb8u1
Severity: normal

Dear Maintainer,

I was attempting to write a script something like a world clock to help 
schedule a task in six time zones.

* What exactly did you do (or not do) that was effective (or ineffective)?
* What was the outcome of this action?
* What outcome did you expect instead?

Steps to reproduce:

# the alias isn't necessary, but it simplifies the demonstration
alias lax="TZ='America/Los_Angeles' date --date=@1469558444 '+%Y-%m-%d %H:%M 
%Z'"
alias syd="TZ='Australia/Sydney' date --date=@1469558444 '+%Y-%m-%d %H:%M %Z'"
lax
syd
date --date "$( lax )"
date --date "$( syd )"

bug symptom:

  Tue Jul 26 11:40:00 PDT 2016
  date: invalid date ‘2016-07-27 04:40 AEST’

expected behavior:
