JerryE on "Is there a getLastChangeDate() function for NewsArticles and Albums?"

I have a custom theme that uses ZenPage and CombiNews. After I publish a NewsArticle or Album, I often make updates to it. In my NewsArticle list and my Album list, I would like to show the original publish date for each item as well as the date that each item was last updated. An example is found here:

I found the getPageLastChangeDate() function for Pages, but I have not found anything analogous for NewsArticles, Albums, or Images. Is there a (easy) way to do this?

I've written my own theme, so I'm not afraid of code, just lazy. <grin>
