Is NTP had this paremeter? not the clock offset value ,but just a error offset value ,in the range of this paremeter it sync. out of it ,it did not sync.

I just read the http://www.eecis.udel.edu/~mills/ntp/html/clock.html,it looks like  the Step interval  paremeter ,but I do not understand what it means, because I was not familiar with English in Computer Scince Tech and I am Chinese.
