In HPUX, xntpd is the daemon which sets and maintains the system time in synchronism with Internet standard time servers. xntpd reads the /etc/ntp.conf configuration file at startup time in order to determine the synchronization sources and operating modes.
The NTP startup script /sbin/init.d/xntpd will start ntp automatically, if you configure the NTPDATE_SERVER variable in /etc/rc.config.d/netdamons.
Sample configuration :
# grep -i ntp /etc/rc.config.d/netdaemons
export NTPDATE_SERVER=”156.12.10.1″
export XNTPD=1
export XNTPD_ARGS=
# grep ^server /etc/ntp.conf
server 156.12.10.1
#
# ntptrace -n
