I have a laptop running Windows XP that does not connect to the Internet and I would like to use a USB GPS receiver as a time source to set the clock. Generally, the laptop will not have access to the open sky so getting a strong, multi-satellite connection is not likely.
Ideally, I would like to be able to have the program detect the GPS receiver and set the clock without intervention from the user.
Is what I'm seeking even feasible?

Commenting vs. answering because I'm no expert at this, but I down own several computers and an old school Garmin GPS that has a serial port interface. Programmatically I don't see why you couldn't do this - in my imagination, you'd write a Service that monitors the serial port then parses the GPS info for the time and sets it. Here's the data format: http://en.wikipedia.org/wiki/NMEA_0183
