Microsoft Security Essentials Update failure (error)

   Microsoft Security Essentials(abbreviated to MSE)  gives not enough information about certain error message, and even it doesn't do. I tried to update the MSE's virus and spyware definitions but at 1/4 of the process, it stopped without any error. It just noticed me that the status is not up-to-date.

   After several tries, I finally found out that the "System TIME" of my machine is wrong. I wish this could be the solution if you meet this situation.
