maxerror is a statistic.  It doesn't control the operation of ntpd in 
any way.  If you can set it, it is only in order to control the value 
that other people read.  That is not something that would be useful to 
do with ntptime unless ntpd was not running.

Also, in practice, if allowed to take its natural value, it is almost 
always many times larger than the true error.

It grows with time, being reset each time ntpd receives a valid time 
from a server.  I think it will be reset to a value that depends on the 
error statistics received from the server.

It is possible that what you really want is "tos maxdistance", but I am 
guessing what you are really trying to do.
