The /var/adm/messages file on an NTP client shows many time reset (step) messages at regular intervals with the sign of the step alternating positive and negative with an amount that is nearly the same.

For example:
Jan 26 11:10:56 crater xntpd[6079]: time reset (step) 0.312899 s Jan 26 11:17:18 crater xntpd[6079]: time reset (step) -0.318915 s Jan 26 11:22:40 crater xntpd[6079]: time reset (step) 0.312903 s Jan 26 11:29:02 crater xntpd[6079]: time reset (step) -0.318887 s Jan 26 11:34:24 crater xntpd[6079]: time reset (step) 0.313149 s Jan 26 11:40:46 crater xntpd[6079]: time reset (step) -0.319057 s Jan 26 11:46:09 crater xntpd[6079]: time reset (step) 0.312988 s
