  <p><strong>Long answer</strong>... <a href="https://craftcms.stackexchange.com/a/1346/45">Ian has some good advice</a>, but the Post Date won't update automatically. Your best solution would be to update the Post Date every time you update something else in the entry. Then your Post Date will essentially represent your "last changed" date.</p>
  
  <p><strong>Bonus answer</strong>... If/when you <em>do</em> build your own plugin, you can look into building your own Element Type. (Just a fair warning... building a custom Element Type is a little more advanced.) When you're setting up your Element Type, you can define which columns appear in that "list" view. One of the native columns in every Craft DB table is "dateUpdated", which contains exactly the information you're looking for. Just output that as one of your columns, and voila!</p>
  
  <p><strong>There's no rush, I can wait answer</strong>... the ability to add custom, sortable columns to the entries (and users, assets, etc.) index pages is coming “Real Soon Now”™.</p>

Answers.Text: Ian this is only true for "Post Date" and "Expire Date". A "Last Modified Date" column is not available, but I can remember Brandon saying it is on "The List" to make the table user editable (add custom fields to it, etc.). Hopefully this will come as a 2.x update.

  **Short answer** is, you can't.
  
  **Long answer**... [Ian has some good advice](https://craftcms.stackexchange.com/a/1346/45), but the Post Date won't update automatically. Your best solution would be to update the Post Date every time you update something else in the entry. Then your Post Date will essentially represent your "last changed" date.
  
  **Bonus answer**... If/when you *do* build your own plugin, you can look into building your own Element Type. (Just a fair warning... building a custom Element Type is a little more advanced.) When you're setting up your Element Type, you can define which columns appear in that "list" view. One of the native columns in every Craft DB table is "dateUpdated", which contains exactly the information you're looking for. Just output that as one of your columns, and voila!
  
  **There's no rush, I can wait answer**... the ability to add custom, sortable columns to the entries (and users, assets, etc.) index pages is coming “Real Soon Now”™.
