As shown in Figure 18-1, the first tabbed
window that appears is for configuring the system date and time and the
NTP daemon (ntpd).
To change the date, use the arrows to the left and right of the month to
change the month. Use the arrows to the left and right of the year to
change the year, and click on the day of the week to change the day of
the week. Changes will not take place until you click the
Apply button.
To change the time, use the up and down arrow buttons beside the
Hour, Minute, and
Second in the Time
section. Changes will not take place until you click the
Apply button.

| | Changing the date and time will change the system clock as well as the
hardware clock. Clicking Apply or
Ok is equivalent to executing the
date and hwclock commands with
the selected date and time.

The Network Time Protocol (NTP) daemon synchronizes the system clock
with a remote time server or time source (such as a
satellite). dateconfig allows you to
configure a NTP daemon to synchronize your system clock with a remote
server. To enable this feature, click the Enable Network Time
Protocol button. This will enable the
Server pulldown menu. You can choose one of
the predefined servers or type a server name in the pulldown menu. Your
system will not start synchronizing with the NTP server until you
click Apply. After you click
Apply, the configuration will be saved and the
NTP daemon will be started (or restarted if
it is already running). If you want this daemon to start automatically
at boot time, you need to execute the command /sbin/chkconfig
--level 345 ntpd on to enable ntpd for
runlevels 3, 4, and 5.
For more information on NTP, read the NTP documentation available in the
/usr/share/doc/ntp-version-number
directory.
Clicking the Apply button will apply any changes
that you have made to the date and time, the NTP daemon
settings, and the time zone settings. Clicking the
Ok button will apply the changes and then exit
the program.
