Blocking ICMP timestamp requests code 13, and timestamp replies code 14

Hi,

I have a cisco router connected to the internet like a bastion host, with different acl's working on it.I have scanned this one with nessus and it say that might be vulnerable to the some information extractions based on ICMP timestamp requests and replies, icmp code 13 and 14. I want to block with some rules on my acl's this posibility, but I do not know how very well.

So, some help from your part would be appreciated.

Regards.
