[clug] GPS and temperature

[Robert Edwards]

Well, don't worry about it's Linux relevance - we can discuss that at
the time... it won't take up the whole evening in any case. I just want
to see what happens and I am sure others will as well! It sounds cool
(excuse the pun).

If anyone has any experience using a GPS receiver as a stratum 1 source
of time for NTP, I would love to hear a talk on that. I started doing
this myself at one stage some years ago, but didn't get too far.

Cheers,

Bob Edwards.
