Timezones incorrect - Home Assistant Green

[kabongsteve]

The problem

The list of Timezones shown in the drop down list is NOT correct for the Australian Timezones.

Nor do they match the named timezones here:

Which is also what this documentation states should be used

All southern eastern states and cities (Sydney, Melbourne, Hobart) are in a single timezone (+10) with DST time as well
Brisbane is also in +10, but without daylight savings

Darwin is +9:30, without DST, but Adelaide is also 9:30 but with DST
