Sarnia allows a Drupal site to interact with and display data from Solr cores with arbitrary (non-Drupal) schemas, mainly by building Views. This is useful for Solr cores that index large, external (non-Drupal) datasets that are either not practical to store in Drupal or may already be indexed in Solr.
This module adds a custom date format to Views, to allow two different date formats to be applied to a single instance of a field, based on an offset from the current time. For example, display any nodes in the past 6 hours as Time Ago (ie, "2 hours ago") and any nodes older than that as MM/DD/YYYY - HH:MM.
This module is a Features export manipulating views and content types needed for my approach to creating a podcast in Drupal 7. This is, currently, a sensible starting point... not an out of the box solution. This feature is dependent on the iTunes_Feed_Formatter module in my sandbox.
