152 # switch back from daylight savings time when other parts of Australia do
153 # on 4 April.
154 #
155 # - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
156 # The change to UTC+11 is being considered as a regular summer thing but

162 # - Mawson station stays on UTC+5.
163 #
164 # In addition to the Rule changes for Casey/Davis, it means that Macquarie
