Jelly Bean Voice Assistant - I live in Washington?

Does anyone else have this?

Try asking it one of these sentences:

"What's the weather like today?"

"What time does the sun rise tomorrow?"

"What's the local time right now?"

I live in London (UK), but for some reason it always gives me answers that are based on me living in Washington. It will tell me the weather in Washington, it will tell me what time the sun will rise in Washington, it will tell me the local time in Washington.

Do other people encounter the same thing? Is this a known bug? Or can I just change my location setting somewhere (I'm an avid Google Latitude user so my phone should know exactly where it is in the world).

Tips, advice, thoughts - all are appreciated.
