+ # From Steffen Thorsen (2010-03-10):
+ # We got these changes from the Australian Antarctic Division:
+ # - Macquarie Island will stay on UTC+11 for winter and therefore not
+ # switch back from daylight savings time when other parts of Australia do
+ # on 4 April.
+ #
+ # - Casey station reverted to its normal time of UTC+8 on 5 March 2010.
+ # The change to UTC+11 is being considered as a regular summer thing but
+ # has not been decided yet.
+ #
+ # - Davis station will revert to its normal time of UTC+7 at 10 March 2010
+ # 20:00 UTC.
+ #
+ # - Mawson station stays on UTC+5.
+ #
+ # In addition to the Rule changes for Casey/Davis, it means that Macquarie
+ # will no longer be like Hobart and will have to have its own Zone created.
