As I said:
"All other servers are with the "noselect" keyword in their lines."
Those servers are for statistics purpose only.
I still have a question unanswered: are there any method to pass over
a long GPS failure (say for several days or more) - supposing the GPS
only source of time and the server have a very good (10E-12) PPS
source (Rubidium or Caesium) ?
I'll try to test a configuration with a generated NMEA RS232 signal
and a very
good PPS source to see what's happening in the event the time reported
by the "GPS" is bad after several days of being good.
