question about updates internal work in case of cache

Hi, Let's suppose a column (name+value) is cached in memory, with timestamp T. 1) An update, for this column, arrives with exactly the *same* timestamp, and the *same* value. Is the commitlog updated ? 2) An update, for this column, arrives with a timestamp < T. Is the commitlog updated ? Than
