According to the latest tz tables, since 1945 every Australian jurisdiction has used 3:00 for the fall switchover if it used DST at all. However, Shanks (1991) gives 2:00 for all the switchovers. When I incorporated Shanks's data, I went with the tz tables, but it'd be nice to check this. Date: Mon, 19 Sep 1994 18:43:57 +1000 From: Robert Elz <kre@munnari.OZ.AU> I don't know if Mar 26 is the 4th Sunday, the last Sunday (next year its both of those) or something else. Judging from the past, it's probably the last Sunday; as far as I know no Australian jurisdiction has ever used a 4th-Sunday rule. We'll find out in 1996, if they don't change the rules again before then. The Vic & Tas rules will need adjusting as well. At least all three should (in theory) become the same now. If my guesses are right, this won't change Tasmania, just Victoria. ACT obviously just goes along with NSW, anything else would be silly. While I was looking into this, I noticed Shanks says that precisely that silliness occurred in fall 1982, causing an error in the tz data for 1982 Sydney (since had I copied the Canberra data, assuming Sydney and Canberra were the same). I'll incorporate a fix into my next proposed patch.
