How to sync NTP time with systemd-timesyncd
systemd-timesyncd is a system service in Linux operating systems that provides time synchronisation with NTP servers. It continuously adjusts the system clock to ensure accurate timekeeping, which is crucial for various system operations, time-sensitive applications, and network synchronisation.
To configure systemd-timesyncd, edit file
|
1 |
vi /etc/systemd/timesyncd.conf |
Add following
|
1 2 3 |
[Time] NTP= FallbackNTP=time.google.com |
Leaving NTP= uncommented and assigned to an empty string resets the list of NTP servers, including any per-interface assignments. This prevents inadvertently moving between smeared and un-smeared time servers. Configuring Google Public NTP as the fallback server will cause it to be selected as the only NTP server.
If you want to use debian maintained NTP servers, use
|
1 2 3 |
[Time] NTP= FallbackNTP=0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org |
Restart systemd-timesyncd
|
1 |
systemctl restart systemd-timesyncd.service |
You can verify NTP server with command
|
1 |
timedatectl show-timesync | grep ServerName |
