+# 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.

The compress and deflate functions produce data in the zlib format, which

19. Ok, so why are there two different formats?
