While there may be other solutions, probably the easiest using standard =

stuff is to run NTP.  NTP supports lots of different reference clocks, =

including a number of GPS receivers.  On my 1.5.1 BETA1 system, there's =

a list in file:/usr/share/doc/html/ntp/refclock.htm.  Note in =

particular Type 20 -- there are a *lot* of NMEA GPS receivers out there.
