Magnus,
I am interested in UTC time for weather satellite reception,
synchronising via NTP. I tried the GPSCON program for the Z3801A but
could never get it to broadcast ntp information on my LAN. Recently, I
have purchased some Sure GPS boards from Sure Electronics
(http://www.sureelectronics.net/goods.php?id=99). David Taylor has a
great page on this at http://satsignal.eu/ntp/Sure-GPS.htm ... but now I
am thinking his time is maybe always 15 seconds off, yes??

Ron,
No, the time is UTC and not GPS, so it's "correct" and not 15s out. To be
sure (and as is good practice in any case), do include an Internet server
or two in your ntp.conf file. Something like this:
# ref-clock drivers - Sure Electronics GPS board
server 127.127.22.1 minpoll 4
server 127.127.20.1 minpoll 4 mode 18 prefer
# Use specific NTP servers
server 0.uk.pool.ntp.org minpoll 10
server 1.uk.pool.ntp.org minpoll 10
server 0.nl.pool.ntp.org minpoll 10
server 1.nl.pool.ntp.org minpoll 10
You can use "ntpq -p" to check the offset of the Sure board relative to
the Internet servers.
Thanks for letting me know that the Web pages were helpful.
73,
David
