I tend also to hang a good gps off a second usb port, if available.
There's a topic for geeks - does anyone else really know (or care)
what time it really is?

25 (or 6) to 4?

Running GPS over USB for timing makes me twitch though - too much
jitter! :)  Use a proper serial or GPIO port, with that you can get down
to sub-microsecond accuracy.
