If your system does not have Internet access or a network time server, manually set the date and time for your system on this screen. Otherwise, use
(Network Time Protocol) servers to maintain the accuracy of the clock. NTP provides time synchronization service to computers on the same network. The Internet contains many computers that offer public NTP services.
The initial display enables you to set the date and time of your system manually.

By default, Fedora is configured to use three separate groups, or pools, of time servers. Time server pools create redundancy, so if one time server is unavailable, your system synchronizes with another server.
To use an additional time server, select
, and type the DNS name of the server into the box. To remove a server or server pool from the list, select the name and click
If your machine is always connected to the Internet through a wired connection, select the
Synchronize system clock before starting service
option. This option may cause a short delay during startup but ensures accurate time on your system even if the clock is significantly wrong at boot time.
Laptops and NTP
Do not use this option with laptop computers that sometimes use wireless networks.
If the hardware clock in your computer is highly inaccurate, you may turn off your local time source entirely. To turn off the local time source, select
Show advanced options
and then deselect the
Use Local Time Source
option. If you turn off your local time source, the NTP servers take priority over the internal clock.
If you enable the
Enable NTP Broadcast
advanced option, Fedora attempts to automatically locate time servers on the network.
