# 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

#

# Magic markers (optional - used by munin-config and installation scripts):
