|Chapter 29. Date and Time Configuration
As shown in Figure 29-2, the second tabbed window that appears is for configuring NTP.
The Network Time Protocol (NTP) daemon synchronizes the system clock with a remote time server or time source (such as a satellite). The application allows you to configure an NTP daemon to synchronize your system clock with a remote server. To enable this feature, select Enable Network Time Protocol. This enables the Server pulldown menu. You can choose one of the predefined servers or type a server name in the pulldown menu. Your system does not start synchronizing with the NTP server until you click OK. After clicking OK, the configuration is saved and the NTP daemon is started (or restarted if it is already running).
Clicking the OK button applies any changes made to the date and time, the NTP daemon settings, and the time zone settings. It also exits the program.
