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
NTP (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
Select the Network Time Protocol tab to

To configure your system to use network time servers, select the
Enable Network Time Protocol option. This
option disables the settings on the Date and
Time tab and enables the other settings on this screen.
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 Add,
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
||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.
