Steps to set a server's time source to the NTP server:

1. Code Block
   timedatectl set-timezone UTC

2. In chronyd.conf, add or modify the following IP address setting.

   1. When using SCS, use the Swarm-internal IP address.
      server {SCS Swarm-internal IP address} iburst

   2. To use a different NTP server:
      server {NTP server IP} iburst
      NOTE:
      This must not be a Windows Directory SNTP server.

3. Restart chrony:

   Code Block
   > systemctl enable chronyd > systemctl restart chronyd

4. Verify that the time sources are correct.

   Code Block
   chronyc sources

   Verify there is an asterisk (*) next to one of the lines, indicating the time has been synchronized. Example:

   Code Block
   language bash
   210 Number of sources = 1 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* telamon.tx.caringo.com 3 8 377 152 +5225ns[+7036ns] +/- 98ms

5. Once the time is synchronized, sync the BIOS clock.

   Code Block
   hwclock --systohc
