I have had mixed results with cell-tower-based location services. The problem is that the closer towers will occasionally have all channels in use, leading your phone to connect to a further-away tower. This causes your phone to think your location has changed. Does your phone support Near-Field Communications? You could mount a couple of NFC tags in your office, swipe one of them as you start work, and swipe the other as you are about to go home.
