<P> On the other hand, Federal legislation yields to state - regulated standard times in many diverse situations . For example, it yields in setting the normal working times of Federal employees, the recognition of public holidays, etc . The Federal government also relies on local times for Federal elections, so that the polls in Western Australia close two or three hours after those in the eastern states . Also, documents to be filed in a Federal Court may be filed based on the local time . The effect of this is that if there had been a failure to file a legal document on time in an eastern State, that document can sometimes still be filed (within two hours) in Western Australia . </P> <P> The 13 zones for Australia as given by zone. tab of the IANA time zone database .
