Skysurfer, not quite. Queensland, NSW, Victoria, Tasmania are all In the Timezone GMT+10. The issue you allude to is that Queensland does not have daylight saving in summer whereas the others do ie clocks are set 1 hour forward.

South Australia’s time zone is GMT+9h30m, and also has daylight saving in summer.

The dates for daylight saving are gazetted by the government each year.

There is also a difference between UTC and GMT (splitting hairs, I know).

What I’d like is metric time as tried briefly in France after the revolution. 10 hours per day, 100 minutes per hour and 100 seconds per minute. And the adopt the ancient Egyptian perpetual calendar - 12 months of 30 days plus 5 holidays at the end of the year, every year the same - and simply accept the seasons shift a quarter of a day per year. The only downside is all the companies making and selling calendars and diaries would be out of a job.

That’s what I regard as an ultimate solution for time and date.
