F5 time Sync. issue

Hi All,

 

 

I am having an issue with my F5 time sync. F5 is showing me incorrect time than actual one.

 

Is someone could help me that how would I get my F5 back into time sync so that it shows me correct time.

 

I hope to get response ASAP as it is a matter or urgency...

 

Please check my attached document to get better idea that what is an error message coming up when trying to re-sync F5 device...

 

 

 

Thanks.
