Special Install Instructions: ----------------------------- Reboot the system after patch installation. This patch adds a new configuration option to the /etc/inet/ntp.conf file. The option is: slewalways yes | no If you turn this option on xntpd will try to always slew the time and will never make large steps backwards or forwards. It is advised that if you do turn on slewalways you also select: disable pll Without this option xntpd will not be able to correct time differences greater than 128ms.
