Use gps for clock correction
Is there a way to use the clock of the gps to correct the hardware clock of the neo? A button sync hw clock in agpsui would be nice. Maybe later it could be a daemon (like ntpd) that does this as soon as the gps chip knows the gps time.

What about ntpd, can it handle gps-data? Yes, with some work: http://time.qnan.org/ Does the FR have access to the PPS signal from the GPS chip? That might get it down to tens of microseconds of clock jitter. :) It looks like gpsd should work as well. Plus, ntp can fall back on NTP over GPRS/wifi/usb if it's been a while since the last GPS connection. It can also set the hardware clock skew so it drifts fewer minutes per day when there's no network or sky.
