System Times of Devices Do Not Match

I have two BIG-IP devices running 13.1.1 and noticed today in the UI that the times do not match. My passive/standby box is 6 seconds ahead. Looking at the configuration they are both using the same NTP server and all devices are in sync.

 

What would be causing this and how might I resolve it?

    Hi,

    did you verifying NTP peer server communications:

    https://support.f5.com/csp/article/K10240

    Please folow this kb to be sure that settings and communication worked fine:

    Verifying the NTP daemon service

    1. Log in to tmsh by typing the following command: tmsh

    2. To show the status of the NTP daemon, type the following command: show /sys service ntpd

    3. Optional: If the NTP daemon service is not running, and you would like to start it, type the following command: start /sys service ntpd

    4. Optional: If the NTP daemon requires a restart, type the following command: restart /sys service ntpd

    5. To exit tmsh, type the following command: quit

    Verifying the communication between the BIG-IP system and the NTP peer server

    1. Log in to the BIG-IP system command line.
    2. To verify the NTP peer server communication, type the following command: ntpq -np

    then follow the KB ...

    regards
