Summary: check_ntp errors when only ntpdate is available

Initial Comment:
When running check_ntp.pl when only ntpdate is 
available, the jitter value remains at zero and causes 
a divide-by-zero error:

Use of uninitialized value in division (/) 
at ./check_ntp.pl line 437 (my line #'s are different 
due to other changes).

The offending line is:
  print ("NTP $key: $answer|offset=$offset, jitter=" . 
$jitter/1000 .     ",peer_stratum=$stratum\n");

I suggest wrapping the jitter calculation in a 'if 
jitter == 0, then print 0, else print jitter/1000' 
construct.
