title: Using computed DateTime columns in Entity Framework
body: <p><code>StoreGeneratedPattern="Computed"</code> works flawlessly on columns of type <code>timestamp</code>. But you can't display a TimeStamp as a human-readable form.</p>
  
  <p>So you can't show the user "This row was modified on <code>{TimeStamp}</code>" because you simply can't parse a SQL Timestamp to DateTime.</p>
  
  <p>Now can I also create computed columns for <code>DateTime</code> columns so I don't need to set it manually?
  <code>myEntity.LastModification = DateTime.Now</code></p>
  
  <p>Not to mention it would be quite error-prone, if some user <strong>really</strong> wanted to do something bad, by simply changing his computers time.</p>
