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. It would be the autumn switchover, we don't have a "fall"... (what's more, almost no, if any, Australian flora is actually deciduous, so its not just a difference in terminology... Nothing native falls in autumn except rain & the temperature!) More seriously, it is, and always has been 02:00 when the switchover occurs, its just that it's 02:00 standard time, not 02:00 wallclock time (so its 03:00 summer time that reverts to 02:00 standard time). In the tz files, that's written as 03:00. At least, that is very explicitly what is in the Victorian legislation, I can't really imagine that its different in the other states, but I can imagine that the legislators don't really think it matters what happens around 02:00 on a Sunday morning, and could have done anything at all. This is also true (to my knowledge) only with respect to the current series of DST (since about 1970) - what happened back in the 40's, or whenever DST previously applied, I have absolutely no idea whatever, it could have been either way. kre ps: to those "unix-admins" at Adelaide Univ who have no idea why they're getting this mail ... nor do I, Mark just included you on the first message. However you are probably going to have to edit your timezone files sometime between now and next Morch. So are all the rest of us.
