The commands and steps to initiate a forceful sync with NTP server may vary based on the distribution you are using.

By default if NTP service is running it will automatically sync the client’s date and time from the NTP server based on the polling interval but what if you want to do a force sync immediately and cannot wait for the NTP client to sync it.

On SuSE Enterprise Linux
The current date and time on my node is

Go to the ' Time & Language → Date & Time ' page. On the right-panel, click on the ' Sync ' button under the Synchronize your clock section. As soon as you click the button, the PC will sync the time with the default Windows time server. The settings app won't allow you to change the default time server. Jul 30, 2020 The Network Time Protocol ( NTP) is a protocol used to synchronize computer system clock automatically over a networks. The machine can have the system clock use Coordinated Universal Time ( UTC) rather than local time. Maintaining accurate time on Linux systems especially servers is a important task for many reasons. Time synchronization may not succeed when you try to synchronize with a non-Windows NTP server.; 2 minutes to read; D; S; In this article. This article provides a resolution for the issue that time synchronization may not succeed when you try to synchronize with a non-Windows NTP server.

My ntp service status

# /etc/init.d/ntp status
remote refid st t when poll reach delay offset jitter
192.168.10.100 10.171.8.4 3 u 1 64 1 0.173 -593996 0.000
10.40.130.1 .INIT. 16 u – 64 0 0.000 0.000 0.000

Checking for network time protocol daemon (NTPD): running

So my ntp client is running, lets change the date and time of my node before doing a force sync

My new date and time

Time to do a force sync

So as you see it immediately sent a request to the NTP server and updated the localhost date and time details from the NTP server

On Red Hat Enterprise Linux 7
Unfortunately ntptimeset is not available in Red Hat Enterprise Linux so we have to try something else

My existing date and time

NTPD service status

# systemctl status ntpd

Now lets change the date and time

First stop the ntpd service

Next initiate a force sync from your NTP server using the below command

Synchronize Time With Ntp Server Ip

Windows Ntp Time Server Address

Now start the NTP service again

Lastly validate if your localhost date and time is updated correctly

Without ‘-u‘ and when NTPD service is running

With ‘-u‘ and ntpd running in the background
