164 Chapter 18. Time and Date Conﬁguration

Figure 18-1. Time and Date Properties

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 Sec-

ond in the Time section. Changes will not take place until you click the Apply button.

Note

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 en-

able ntpd for runlevels 3, 4, and 5.
