I'll call your attention once again to the fact that despite certain
people's protests to the contrary, every state government website calls
it that, and the government acts in NSW, Tasmania, and SA, respectively,
are called Standard Time Amendment (Daylight 
Saving) Act 2005, Daylight Saving Act 2007, and the Daylight Saving Act
1971.

Even if it doesn't have any "official" standing (but then, neither does
"Eastern"), you can't credibly argue it 'means nothing'.
