iPhone time goes back 2 hours when at home

When I come home, my iPhone time goes back two hours (so if it is 9 o'clock, my phone turns to 7 o'clock in the apartment). When I walk about 20 feet outside of our apartment, the iPhone goes back to normal time. My partner's iPhone also suffers an extreme delay (anywhere from 30 minutes to an hour or more) in receiving text messages inside the apartment. What is also odd is that when I look at other cities in EST on the clock app the time reads correctly even though we are in EST and the clock displaying on the phone falls back 2 hours. Any thoughts on what is doing this?

What ios do you have? Is it jailbroken?

edited: Sorted the problem. Seems to have something to do with being connected to our wireless network at home. My partner's older iphone doesn't have this problem, but mine does for some reason. Once I disconnected from the wireless, the time was correct.
