Hi!
Has anyone here configured the Acutime Gold GPS from Trimble
(http://www.trimble.com/timing/acutime-gold-gps-antenna.aspx) with
NTP?
After converting RS-422 to RS-232 what do I need to with on the NTP side?
Many thanks!
Cheers,
Miguel

If you want to clear a very large error by a pure slew, the best way is
not to start ntpd until you have cleared the error, but, instead, to use
whatever utility your OS uses to access
