Why JVM shows wrong time zone for (UTC+02:00) Istanbul?

JVM does not show true date time and time zone for (UTC+02:00) Istanbul.

For example: Now time is 12:30 PM in Istanbul.

Change System Time Zone to (UTC+02:00) Istanbul

System Date: 12:30 PM 03.07.2013

Java ouput: 05:00:00 VET 03.07.2013

JVM uzer.timezone: America/Caracas

Change System Time zone to (UTC-08:00) Pasific Time(US&Canada)

System Date: 02:30 AM 03.07.2013

Java ouput: 02:30:00 PDT 03.07.2013

JVM uzer.timezone: America/Los_Angeles

Change System Time zone to (UTC+02:00) Jarusalem

System Date: 12:30 PM 03.07.2013

Java ouput: 12:30:00 IDT 03.07.2013

JVM uzer.timezone: Asia/Jerusalem

This is my Java Environment: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01, mixed mode) Windows 8

Is there any one to explain this difference?

Thanks
