If your ntp server can't sync time, your test is actually doing it's job 
by crying.  You can add some retries in there if you can't get the core 
issue solved.

I can't say better, but i'd use some perl to actually query the ntp. 
You can jam it all on one line easily.

perl -MNet::NTP -e '
for($i; $i<3; $i++){
 %r=get_ntp_response("127.0.0.1");
 if( $r{Stratum} <= 4 && $r{"Receive Timestamp"} >= time()-600 ){
  $s=1;
  last;
 }
 sleep 60;
}
print "error with ntp server\n" unless $s;'
