To setup Debian Linux to synchronize its date and time with an NTP (Network Time Protocol) server, follow these steps:
sudo apt install ntp
This will install the ntp package, which includes the ntp daemon (ntpd).
Configure the ntp daemon. Open /etc/ntp.conf file with root privileges:
sudo nano /etc/ntp.conf
In the file, find the lines that specify the ntp servers to use. You can uncomment these lines and replace the default servers
with the ones you want to use. For example:
server time.google.com
Save and close the file.
Restart the ntp daemon:
systemctl restart ntp
To verify that your Debian Linux system is synchronizing its date and time with the ntp server, you can run the following command:
timedatectl status
