have you set both active and standby node to ntp time server with correct time?

if the difference to ntp server is less than 1000 seconds, the system should drift the time by itself until they match the ntp server.
larger than 1000 seconds will need restart ntpd.

Thanks for the response,  HA Active F5 is showing 7 sec ahead. Will wait for the system to sync time with ntp server automatically. In case time sync still fails, will restart ntpd daemon cause any production impact or any HA impact.
