Openntpd output looks like this: 

Nov 6 23:28:15 cloud1-ceph1 ntpd[1572]: adjusting local clock by -0.325597s 
Nov 7 00:09:48 cloud1-ceph1 ntpd[1572]: skew change 36.903 exceeds limit 
Nov 7 00:37:12 cloud1-ceph1 ntpd[1572]: skew change -21.291 exceeds limit 
Nov 7 01:06:15 cloud1-ceph1 ntpd[1572]: skew change -17.565 exceeds limit 
Nov 7 01:28:06 cloud1-ceph1 ntpd[1572]: skew change -7.156 exceeds limit
