Java needs more timezones to support platform timezones and deal with exceptional DST rules.

Australia/Broken_Hill (== Australia/Yancowinna)
	GMT+09:30. Follows the exceptional DST rules in 2000. Currently mapped to Australia/Adelaide which doesn't use the exception. Note that Solaris zoneinfo fixes this in Solaris 8.

Australia/Hobert (== Australia/Tasmania)
	GMT+10:00 w/o the exception. (TimeZoneData doesn't have this.)
