FULL PRODUCT VERSION :

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
After introduction of Daylight Savings Time in Western Australia, I used the Timezone Updater Tool to update the timezones. I got incorrect results parsing and formatting times in this timezone.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Run the Timezone Updater Tool to make sure the latest timezones are available
2. Run Test code below for timezones Australia/Perth and compare running it for Australia/Melbourne

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Output:
Success
ACTUAL -
Output:
20071112020000 Coordinated Universal Time -> 20071112110000 Western Summer Time (Australia) in DST
20071112030000 Coordinated Universal Time
since epoch before: 1194832800000 since epoch after 1194836400000

REPRODUCIBILITY :
This bug can be reproduced always.
