HTC Incredible :: Location On Clock - Weather Widgets

Generally my location is detected normally but on occasion i get a number instead of the town i am in on the home screen clock widget. Same goes with the weather widget. I know its not a problem with the town information because sometimes it works and generally does so after being at the location for awhile. However today, for example, my location at work simply displays as "5". It has not updated itself after about 8 hours and counting. Friday it was fine.
