You need to add lines here:
restrict time.nist.gov mask 255.255.255.255 nomodify notrap noquery restrict ns.arc.nasa.gov mask 255.255.255.255 nomodify notrap noquery restrict tick.usno.navy.mil mask 255.255.255.255 nomodify notrap noquery

Wasn't there a line:
server 127.127.1.0 # local clock
here originally?
fudge 127.127.1.0 stratum 10
