In looking at /var/log/tracking.log I see
Date (UTC) Time IP Address St Freq ppm Skew ppm Offset L Co Offset sd Rem. corr.
==================================================================================================
2015-07-20 20:13:34 10.64.1.25 2 30.665 0.177 -3.530e-06 N 2 6.553e-05 1.151e-05
I am having trouble understanding the field 'Offset sd' and what i represents. It is consistently an order of magnitude greater in value than the 'Offset' field so I presume it is not the standard deviation of offset.
"chronyc tracking" displays a result for RMS Offset consistent with 'Last Offset' as seen here:
Reference ID : 10.64.1.25 (fleur.lan.seaviewsound.co.nz)
Stratum : 2
Ref time (UTC) : Mon Jul 20 20:20:34 2015
System time : 0.000007302 seconds slow of NTP time
Last offset : +0.000004646 seconds
RMS offset : 0.000005560 seconds
Frequency : 30.482 ppm fast
Residual freq : +0.004 ppm
Skew : 0.082 ppm
Root delay : 0.000237 seconds
Root dispersion : 0.000094 seconds
Update interval : 16.2 seconds
Leap status : Normal
Any help appreciated
