Hello,

Which config switch,file does it affect? I want to turn it on on my CentOS machine without xauth , just editing config files , i was hoping it could be in /etc/sysconfig/ntpd but no.
most likely, the system-config util is setting that option in /etc/sysconfig/ntpd which by default reads...
# Drop root to id 'ntp:ntp' by default.
OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid"
# Set to 'yes' to sync hw clock after successful ntpdate
SYNC_HWCLOCK=no
# Additional options for ntpdate
NTPDATE_OPTIONS=""
if -x is /not/ set in OPTIONS, it calls /usr/sbin/ntpdate with various parameters, this hard sets the system time to the NTP server time. if -x /is/ set, it does the time step thing
if SYNC_HWCLOCK=yes, then it invokes sync_hwclock in the /etc/init.d/ntpd script, which in turn runs /sbin/hwclock with various options as specified.
