The "Your clock is too far off NIST time" Error

Symptoms

When trying to update the cPanel license, you encounter an error similar to the following. 

[root@server ~]cPs# /usr/local/cpanel/cpkeyclt
Updating cPanel license...Done. Update Failed!
Error message:
The cPanel license server said that a license could not be issued for your server (500).

The exact message was: Your clock is too far off NIST time. (203.0.113.2)
[root@server ~]cPs#

Description 

This suggests that the system time is incorrect. You can confirm this by running /usr/bin/timedatectl and comparing the output with the correct time and date for both the local and the assigned time zone.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the following command.

   /usr/local/cpanel/scripts/rdate

   Please note that if the above command doesn't work, you should contact your hosting provider to have the issue corrected.
