What do you think of my ntp.conf ?


These istructions are contained in my ntp.conf of my server:

logfile /var/log/ntp.log
restrict default ignore
restrict 127.0.0.1
restrict server-A mask 255.255.255.255 nomodify
restrict server-B mask 255.255.255.255 nomodify
# A,B : my internal time server

restrict external-time-server-1 mask 255.255.255.255 nomodify noquery
notrap nopeer
restrict external-time-server-2 mask 255.255.255.255 nomodify noquery
notrap nopeer
restrict external-time-server-3 mask 255.255.255.255 nomodify noquery
notrap nopeer
restrict external-time-server-4 mask 255.255.255.255 nomodify noquery
notrap nopeer
restrict 127.127.1.0 mask 255.255.255.255

server external-time-server-1
server external-time-server-2
server external-time-server-3
server external-time-server-4
# NTP server in Internet

server  127.127.1.0     # local clock
fudge   127.127.1.0 stratum 10
driftfile /var/lib/ntp/drift


What happens if I erase "server 127.127.1.0" and "fudge   127.127.1.0
stratum 10" istructions ?
My internal servers A,B (which retrieve time from this server) need
these istructions to synchronize themselves ?
