Well,
follow the example. (Remember, we can do this different )

First of all, you have to add a new column to your table

Alter table INFORMATION add LastUpdate datetime null

Then you create the Trigger (take care, you have to declare the variable Name like your table)

Create TRIGGER trig_Information
ON Information
FOR UPDATE 
AS 
BEGIN
    declare @Name as varchar(100) /*Look up your column type*/

    select @Name = i.Name from Inserted i

    update Information set LastUpdate = getdate() where Name = @Name 
END

So, everytime someone update any register of this table, the trigger will update the field LastUpdate with the date/time of the operation.

MS. If your table has more than one PK, specify at the where clause.
