Dear All,

in the my last test (I hope) I working in final condition, and my raspberry is not connected to internet.
In this situation my ntpmon is:

     remote           refid      st t when poll reach   delay   offset   jitter
 SHM(1)          .PPS.            0 l    -   16    0   0.0000   0.0000   0.0010
 SHM(0)          .GPS.            0 l    -   16    0   0.0000   0.0000   0.0010
ntpd ntpsec-1.1.6+ 2019-07-13T10:40:27Z        Updated: 2019-08-08T20:32:04 (8)
 lstint avgint rstr r m v  count rport remote address
      0   1.16    0 . 6 2    730 42642 localhost

for all time.

my /etc/ntp.conf file is:

#pool us.pool.ntp.org iburst

driftfile /var/lib/ntp/ntp.drift
logfile /var/log/ntp.log

restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
restrict 127.0.0.1 mask 255.255.255.0
restrict -6 ::1

# GPS PPS reference (NTP1)
server 127.127.28.1 minpoll 4 maxpoll 4 prefer true
fudge 127.127.28.1 refid PPS
fudge 127.127.28.1 flag1 1

# GPS Serial data reference (NTP0)
server 127.127.28.0 minpoll 4 maxpoll 4
fudge 127.127.28.0 time1 0.9999 refid GPS

What am I doing wrong?
