Attachment: Hand-rolled rule that should be close enough

Australia/Perth introduced DST in October 2006, for a three year trial.
This is in the 2007a Olson data, but is too complex for vzic to express accurately without using --pure.

See http://www-1.ibm.com/support/docview.wss?rs=899&uid=swg21250452

The accurate rule is:

This would make Outlook 2000 and 2003 fail.
