I think its quite clear what the most common standard is. AEST / AEDT 
(and likewise westward) are the national standards. It is also a clear 
and unambiguous selection for those unfamiliar with local custom, and to 
the majority of Australians that come to this list.

And to finally clarify it and put it everything in perspective, the site 
from the communityrelations.lawlink says the standards follow the above 
rules, though "summer time is commonly expressed as EDST".

When the approved standard is as in my first line, but a common usage is 
often "EDST", then you go with the goverment standard, not the common 
usage. This is not the USA we are talking about here - its Australia, 
where its citizens tend to somewhat respect the national laws and 
standards used by the government they have voted for.

Are people suggesting we should go with Daylight Saving's' time (which 
is the 'common expression' in many parts of the USA) when the standard 
is Daylight Saving (no 's') time? Or worse yet, when some people use 
one, and some the other - we should then impose a third ambiguous 
expression upon users of our database, as we are doing now?

I'm tired of this debate, as we all are, but clearly the noise can 
reduced by using the AEST/AEDT (and like) abbreviations over what is 
defined now.

It clearly states on one of the examples presented that the Australian 
standard is as above but in some calles
