The timezones for the rest of Australia are lacking
(no daylight savings options), plus all they are
named with acronyms not used in Australia (WAS, CAS,
EAS, instead of the proper AWST, ACST, AEST). The
second patch corrects that.
I have seperated the two patches, because changing
the acronyms may have some undesirable effects on
existing user configs. I don't know the Slash code so
I am merely speculating.
