Client does not sync date with ntp servers
We had a network problem a couple of days before that caused 1 interface to down and up. But today I have noticed that our date is wrong, our system have 4 servers and the other 3 are OK.
I used <date> command, the result is:
Code:
Fri Jan  2 17:57:55 ICT 1970

I have tried set date to be the same as other with this command:

Code:
date 1008094412

and received:

Code:
Fri Jan  2 17:59:37 ICT 1970
WARNING: date can only be changed by ntp 1 1

Can anyone help me on this Smilie

I have just reboot the server and there's nothing new. I have just run into this prompt:
"Time-of-Date Chip had incorrect date"
Please take a look and help me on this, ntp problem is really a serious one.
