Download neko_openntpd-3.9p1.tardist from nekoware or download ntp from freeware.sgi.com
ntp on timed off timeslave off
edit /etc/ntp.conf add a server line for the timeserver you want to use.
See NTP.org site for more information or download ntp source from the above ntp.org site and compile and install it.
NOTE: neko_openntd seems to install a different package than specified above which is possibly the SGI Freeware version. Instead, I had to:
chkconfig neko_ntpd on
and edit /usr/nekoware/etc/ntpd.conf. You may alway wish to force a service restart (without rebooting)

Turn timeslave on:
chkconfig timeslave on
Edit /etc/config/timeslave.options to include a time server:
Start it up as root (or reboot if you prefer):
/etc/init.d/network stop; /etc/init.d/network start
And that's it. Every once in a while in your SYSLOG you should see messages like:
Oct 18 00:33:43 5D:Komugi timeslave: date changed from 10/18/04 00:33:33
Refer also to the util/timetrim.c program for some older SGI models and UNICOS based Cray super computers in the NTP reference distribution.
