It's the "-g" parameter, I believe:

http://www.eecis.udel.edu/~mills/ntp/html/ntpd.html

-g
     Normally, ntpd exits with a message to the system log if the offset 
exceeds the panic threshold, which is 1000 s by default.  This option 
allows the time to be set to any value without restriction; however, 
this can happen only once.  If the threshold is exceeded after that, 
ntpd will exit with a message to the system log.  This option can be 
used with the -q and -x options.  See the tinker command for other options.
