I think the long names of the Australia time zones should be revisited 
to be consistent with the abbreviation changes. The new abbreviations 
follow the S[tandard] and D[aylight saving] convention rather than the 
S[tandard] and S[ummer time] one. The long names, such as "Eastern 
Summer Time (Queensland)", no longer make sense.

On the other hand, you will need to access impact of the name changes, 
including abbreviations. Also, if you change the long names, their 
translations will need to be changed as well.
