Possible... A better solution there would be for me to finally add support
for gps data via GPSD, as GPSD already has the ability to discipline the
system clock via NTP. However, this is only useful if the 1pps line is
connected. GPSDs time service manual notes that the jitter resultant from
using timing based on the start of the NMEA packet burst can result in
fairly inaccurate timing. Anyway, something to look into...

I'm trying to avoid too much feature creep in chase mapper, especially when
there are already solutions to some of these problems provided by other
software!

Cheers,
Maek
