I believe you are telling the client to ignore time synch packets from
your server. You need another restrict line in your client's ntp.conf
file. Try something like:
server 192.168.0.35
driftfile /etc/ntp.drift
restrict default ignore
restrict 192.168.0.0 mask 255.255.255.0 noquery notrust
restrict 192.168.0.35 nomodify
With this your client will ignore time packets from any machine except
your time server. Even localhost won't be able to change internal ntpd
parameters with this setup. Unless, of course, someone changes their IP
and masquerades as your time server.
