=head1 VERSION
Revision 0.1 2008/08/23 13:06:00 joti
First version only chronyc tracking, autodetection included.
Revision 0.2 2008/10/11 16:09:00 joti
Added scaling of other values to match with frequency, added more description to fields
Revision 0.3 2014/02/16 zjttoefs
reduce forking by using awk
do not limit output precision
add stratum monitoring
detect slow/fast time or freqency and adjust sign of value accordingly
remove commented out code
