When time zone support is on even when I am on Jerusalem, when i create an appointment the time zone for the appointment is immediately changed to Gaza and even when I change it manually it returns to Gaza.

I have a 4s iPhone on IOS 6.0.1 with an Israeli Cellular provider.

I use Gmail services an exchange to sync my colander contacts and mail.

When the time zone support is set to ON in the Settings->mail, Contacts, Calendars->Time Zone Support

The time zone is showing Jerusalem (I am located in Tel-Aviv)

When I create a new Appointment, It Immediately changes the time zone of the appointment to Gaza.

Even if I change it back to Jerusalem it changes back to Gaza every time.

Only when the time zone support is set to OFF in the Settings->mail, Contacts, Calendars->Time Zone Support

The time zone in Gmail is ok and does not appear on the iPhone. (This is ok)

Dose any one know how do I make the iPhone not change the time zone to Gaza? And still keep the time zone support on?
