It's important that your Funtoo Linux system has an accurate clock. NTP (network time protocol) can ensure your clock is accurate at all time.

{{Important|Do you want a particular build of Funtoo Linux but do not see it here? Let us know what you need, and we will likely add it for you. [https://bugs.funtoo.org Create a bug report] requesting the build you need. To see what options there are, see our [[Corei7|Intel Core i7]] subarch page, which has a lot of builds listed.}}

Chronyd can then be started immediately by running <code>rc</code> to start all new services:
+

<console>
+
###i## rc

</console>
+
 
+
Because Funtoo Linux starts network daemons without waiting for an Internet connection to become available, and because chrony will attempt to synchronize the clock over the Internet when it first starts, you must manually configure chronyd to be dependent on whatever method you use to enable your outbound network connectivity. For example, if using <code>dhcpcd</code>, add the following to <code>/etc/conf.d/chronyd</code>:
+
 
+
<pre>
+
rc_need=dhcpcd
+
</pre>
+
 
+
You should notice a marked improvement in your system clock's accuracy. If your system time was off by a significant amount, <code>chronyd</code> will gradually correct your clock while the system runs.
