It is "Summer Time" (Eastern Summer Time) which is what it is called in the legislation. It is also (if unimaginative) a rational name, unlike "daylight saving" which is gibberish. | Again, this is not about just choosing a /new/ set, but it is about | one that uses one acronym for each zone during daylight saving time. Why? | How would you demonstrate "official government backing" if not by | selecting a subset of official government websites? You would (presumably) ask the appropriate govt department(s) for a ruling (and appropriate here is nothing from the commonwealth govt, except if you're asking about ACT, and certainly not the Bureau of Met). kre
