As most modern operating systems, IRIX offers the possibility
to sync the internal clock with an external time server. There
are many public time servers you can use. Especially if you work
in a LAN, it can be rather important that all computers do have
the same time and date - I mean exactly the same time and date.
Otherwise shared ressources (like files) can't be synchronized
properly between clients.
The standard technique used for synchronizing computers clock
using TCP/IP uses the NTP protocol - 'Network Time Protocol'.
This page explains how to enable automatic time synchronisation
Enabling the NTP Client
Unfortunately IRIX does not have NTP-support out of the box,
you first have to install the freeware ntp package (available
First of all you have to disable any other time-synchronisation.
Especially the daemons timed and timeslave
have to be deactivated by typing
>> chkconfig timeslave off
>> chkconfig timed off
Then of course you have to enable the ntp-daemon by typing
>> chkconfig ntp on
Then you probably want to change the default time-servers in
# Start or stop the SGI Freeware NTP daemon.
# Set custom options in /etc/config/ntp.options to override
# default configuration.
# ntpd daemon does not fiddle with timetrim.
# If /etc/config/ntp.timetrim exists, the contents will be used
# to set the kernel timetrim. BE VERY CAREFUL.
# Built for SGI Freeware by Vince Levey <email@example.com>
# $Revision: 1.1 $
# Add a list of NTP servers to set the boot time to.

Setting the Timezone
Another important setting you might want to change is the timezone,
which is stored in /etc/TOMEZONE.
