4s auto time update

If I set my iPhone 4s to set time and date automatically, under general settings, the phone switches to New York time zone and i can't get it to change to London or any other time zone unless i turn it back to manual setting,I bought the phone direct from Apple [UK], and have used it in Florida recently [new york time zone] but can't remember if I had this problem before my trip ?

Try this
Go to location services - system services and turn off setting time zone

A lot of people have this I think it's a bug

 

Sorry but can't find system services, all I can see in notifications are my apps

 

Found it it's under location services ,turned on now ok ,thanks
