ICMP TIMESTAMP

[Felipe Maya]

Hello people.

I am trying to take data timestamp from an icmp sk_buff, the icmphdr don´t 
have this information.  I feel that timestamp information could be in data 
sk_buff. How take this information?? Is it wrong?

struct tstamp{
     __u32 times[3];
} ;


{
   struct tstamp *tstamp;

   tstamp = (struct tstamp *)(skb->data + skb->hh.iph->ihl * 4 + 
sizeof(struct icmphdr));

}

If it is ok, why can´t i take the data timestamp?

THANKS  for any help.
