From 1a18ca47716aaa8da9dab27cee08f8b9c0c3356a Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 14 Sep 2010 17:39:17 -0500 Subject: Add last modified date to news This will come in handy when determining whether resources are out of date, such as our news RSS feed. Also bump the Date fields to DateTime fields for sake of sorting and if we have more than one news item on the same date.
