The status should show 
active (running)
. If there are no errors, and the 
date
 
command reports the correct time, then there should be nothing you need to do 
here if all you're wanting to achieve is to make sure that your clock is accurate.
If you'd like to set up your own NTP server for other nodes on your network to 
synchronize time against, then there's more work that you'll need to do. If you're 
wondering why you may want to run your own NTP server, one reason might 
be that if only one server on your network synchronizes with an external server 
(which is what NTP does), then you minimize the number of devices attempting 
to communicate with an external server. It also gives you more control over your 
network. Running your own NTP server is completely optional, but it may benefit 
you to do so. If this is something you'd like to set up, continue reading through 
this section.
To set up an NTP server, you will need to install the 
ntp
 package:
sudo apt install ntp 
This will actually trigger the 
systemd-timesyncd
 package to be removed, as 
ntp
 
replaces it. But once installed, the 
ntp
 daemon will immediately start and will keep 
your time up to date just like 
systemd-timesyncd
 did. To verify, check the status of 
the 
ntp
 daemon with the following command:
systemctl status ntp 
The output should show that 
ntp
 is running:
