Replication Timestamp

Hi,
from the url-- http://support.microsoft.com/default.aspx?scid=kb;en-us;820675 I did the steps to implement the replication. However, i did not include a timestamp column in the tables. Is it important as to what would happen if i did not include this? I have the rowguidcol though. I thought this could would help to identify the various row.
Help pls?

:confused:Hey looney79,

Having a timestamp will help you solve problems down the road when replication breaks. You can also set up some form of alert using that timestamp and the getdate() function to set yourself up with some alerts.
