F5 - System Times of Devices Do Not Match

Hi,

I need some help, as i am seeing below "System times of devices do not match" error in F5 running on HA. Please let me know how to troubleshoot this without impacting F5 production traffic.  

Below error:

System Times of Devices Do Not Match

One or more system times of the devices in the device trust do not match the system time of the local device. Auto or manual device group sync operations may fail.

Verify that the NTP Settings on all devices are properly configured and that the system times are equal.
