I could reproduce this problem by specifying the system property
user.timezone:

$ java -Duser.timezone=Europe/Zurich DateFormatTest
Same time zone
Dates don't match? Wed Mar 03 01:12:54 GMT+01:00 2004 != Wed Mar 03 02:12:54 GMT+01:00 2004
Different time zone
$ java -Duser.timezone=Asia/Yakutsk DateFormatTest
Same time zone
Dates don't match? Wed Mar 03 09:20:32 GMT+09:00 2004 != Wed Mar 03 10:20:32 GMT+09:00 2004
Different time zone

I think this problem has something to do with the time zone that
has daylight saving time which starts from March.
