Just to clarify Joe: Are you saying it can be done by letting gpsd
control the GPS and let NTP talk to gpsd?
I know GPS can be a clock source, but gpsd is a service that owns the
GPS and hands out data to programs on the system/network that need GPS
data. I really don't see how that's compatible with rather strict NTP
timing requirements.
